(CNN) - A roundup of quotes from the Sunday political talk shows, as compiled by the CNN Wire:
"I think that the U.S. government provides an awful lot of aid to Pakistan, provides a lot of military support to Pakistan. And to send a clear message to Pakistan that this is important, to them as well as to us, that I think - that message has not been sent."
-Sen. Barack Obama, on how to engage Pakistan to help improve security in Afghanistan, speaking to CBS' "Face the Nation"
"I think the consequences could be very dangerous in that regard. I'm convinced at this point in time that coming - making reductions based on conditions on the ground are very important."
-Adm. Michael Mullen, Chairman of the Joint Chiefs of Staff, on the possibility of a timeline for U.S. troop withdrawal from Iraq, speaking to "Fox News Sunday"
"I think it sends a signal that there is one, that eventually we do want to bring our troops back, and that... with where we are, conditions are improving in Iraq."
-Mullen, on President Bush and Iraqi Prime Minister Nuri al-Maliki's talk of a "general time horizon," speaking to "Fox News Sunday"
(CNN)– Both parties' presumptive nominees praised former Vice President Al Gore as he challenged the nation Thursday to transition completely to renewable and carbon-free energy within the next decade - but parted ways on some of Gore's recommendations.
"For decades, Al Gore has challenged the skeptics in Washington on climate change and awakened the conscience of a nation to the urgency of this threat," Obama said in a statement Thursday.
Obama's environmental proposals mimic many of Gore's own: he would implement an economy-wide cap-and trade program to reduce greenhouse gas emissions, and plans to make the United States a leader in the global effort to combat climate change.
But John McCain reminded reporters he and Gore hold very divergent views on the use of at least one renewable energy source.
"I've admired the Vice President on this issue," McCain said Thursday. There may be some aspects of climate change that he and I are in disagreement on but overall - I mean, I've always been a supporter of nuclear power and he has not agreed with that."
The Arizona senator co-sponsored cap-and-trade legislation introduced last year - but has criticized later versions of the bill for failing to include further incentives for nuclear power, saying the nation would not make progress in ending global warming unless nuclear energy was greatly expanded.
McCain also continued to contrast his environmental policy with Obama's.
"Let me just say again, Sen. Obama, no storage and no reprocess. And that's nuclear power. No drilling offshore. That's a way of finding oil and gas reserves. Dr. No," McCain said.
TAYLOR, Michigan (CNN) – Could Barack Obama ask a former vice president to reprise his role on the Democratic ticket?
At a Michigan campaign event Tuesday, a student reporter asked the presumptive Democratic nominee if he would consider asking Al Gore to serve as his running mate.
Obama, who has kept mum on his vice presidential plans, sidestepped the question. "I have just started looking through possible candidates. I haven't made any decisions. I'm getting some recommendations,” said the Illinois senator. “Obviously Al Gore is a great public servant, he was a great vice president. He may not want to be vice president again, since he's already done that for eight years, but certainly he's somebody that I'll be getting advice from as we go forward and hopefully he'll help me when I'm president."
The 2000 Democratic presidential nominee, who officially endorsed Obama Monday, said in December that he might jump back into the political fray – but only in a bid for the top spot. A third term as vice president would mean Gore had spent more time in the office than anyone in U.S. history.
DETROIT, Michigan (CNN) – Barack Obama defended Hillary Clinton at a Michigan unity rally Monday night that featured former Vice President Al Gore - and some off-message audience booing at the mention of the New York senator's name.
After joking about the extended Democratic primary season – “I was planning to run for the '08 election, not the 2012 election!" – Obama responded to some vocal Clinton critics in the crowd, who had reacted to praise for the senator from both the presumptive Democratic nominee and Michigan Gov. Jennifer Granholm, a longtime Clinton supporter.
"I want everybody here to be absolutely clear - I want everybody here to be absolutely clear - Senator Clinton is one of the finest public servants we have in American life today," said Obama, noting her work on behalf of children's rights and universal health care.
"She has been on the right side of just about every battle that we have fought - she has, in her own words, shattered a glass ceiling into 18 million pieces. ….She is worthy of our respect, she is worthy of our honor.
(CNN) - Former Vice President Al Gore endorsed Democratic presidential candidate Barack Obama on Monday, urging Americans to reject what he called the Bush administration's legacy of "incompetence, negligence and failure."
"Americans simply cannot afford to continue the policies of the last eight years for another four," Gore, the party's 2000 presidential nominee, told Obama supporters at a rally in Detroit, Michigan.
Perceived as a senior statesman in the Democratic party, Gore brings a certain force to Obama's campaign, political analysts have said.
Monday marked Gore's debut in the 2008 election; he had not weighed in while Obama was still battling Sen. Hillary Clinton.
Amid thousands of cheering supporters, Gore began by addressing head-on the criticism that Obama doesn't have enough experience to lead the nation.
The former vice president turned Nobel Prize winner playfully said he recalled one Republican nominee wondering out loud whether his Democratic rival for president was "naive and inexperienced."
"And yet another said the United States cannot afford to risk the future of the free world with inexperience and immaturity in the White House," said Gore. "Who were they talking about? Every single one of those quotes came from the campaign of 1960, when the the Republicans attacked John Fitzgerald Kennedy for allegedly lacking the age and experience necessary to be president."
(CNN) - After remaining neutral throughout the Democratic primary season, former Vice President Al Gore is officially backing Barack Obama's presidential run, and will appear with him at a Michigan campaign event Monday night.
"A few hours from now I will step on stage in Detroit, Michigan to announce my support for Senator Barack Obama," said the 2000 Democratic presidential nominee in a fundraising e-mail sent to supporters Monday. "From now through Election Day, I intend to do whatever I can to make sure he is elected President of the United States."
Former presidential candidate John Edwards also announced his decision to endorse Obama at a rally in the crucial fall swing state.
WASHINGTON (CNN) – Democratic strategist James Carville told CNN Wednesday that former Vice President Al Gore should reprise his role as the No. 2 on a Democratic ticket.
“I think if I was Senator Obama I would say the biggest economic problem we face is the biggest national security problem and the biggest environmental problem,” Carville told CNN’s Wolf Blitzer on the Situation Room. “And if I were him, I would ask Al Gore to serve as his vice president, his energy czar, in his administration to reduce our consumption and reliance on foreign energy sources.
“That would send a signal to the world, to American people, to Congress, to everybody, that America's getting serious about this horrendous problem that we face.”
Gore said in December that he might jump back into the political fray – but only in a bid for the top spot. A third term as vice president would mean Gore had spent more time in the office than anyone in U.S. history.
Later, the political strategist – who supported Hillary Clinton’s presidential bid – admitted he’d rather see her name on the ballot under Obama’s this fall. “Obviously, I would be delighted if he picked Senator Clinton. I'm trying to be provocative in one sense,” said Carville.
Conservative commentator Bill Bennett dismissed the idea. “It's been said that the vice presidency isn't worth a bucket of - you know the rest of the line. To do it twice, I don't know that someone would want to do it twice. He's been there, done that.” He added that Gore would probably not want to put himself “in a subordinate role” – and that Obama needed a foreign policy expert as his running mate.
Both Carville and Bennett are CNN contributors.
(CNN) - It's an endorsement that both Hillary Clinton and Barack Obama would love to score, but Al Gore has remained firmly neutral - even as the Democratic presidential race drags on months longer than expected.
Many have speculated why Gore, one of the party's most popular figures, has decided to stay on the fence, but the former vice president said Tuesday the reason is really quite simple - and he still may yet come out for a candidate.
"My purpose in not endorsing a candidate is nothing elaborate," he told National Public Radio. “I’m simply watching and listening to the campaign. As a delegate to the convention I will cast my vote at the proper time. I haven’t ruled out making an endorsement prior to that time, but I haven’t been moved to do so.”
Gore added, "I have respect for both candidates, they both have strengths, and I’m simply listening and watching like a lot of people."
The party's 2000 presidential candidate is easily the most sought after remaining undecided superdelegate and his is perhaps one of the few remaining endorsements that could significantly alter the state of the race. But several political observers have suggested Gore is remaining neutral should he be called in to play the role of "party elder" and forge a compromise between the two candidates.
"I don't like that phrase party elder," Gore said of that suggestion. "I am not anxious to be playing that role. I just turned 60, which is the new 59. I am just a voter, and a recovering politician, and watching it carefully. (TIME.com: Is Al Gore the Answer?)
"I don't know if that role really exists," Gore added. “I think the odds are overwhelming that it will tip rather decisively in one direction or another before the convention even meets.”
(CNN) - Al Gore has a spot in a potential Barack Obama administration, the Illinois senator said Wednesday.
Asked at a campaign event if he'd consider Gore for his cabinet, Obama immediately said he would.
" I will make a commitment that Al Gore will be at the table and play a central part in us figuring out how we solve this [climate change] problem," Obama said.
Obama also said he talks with the former vice president on a "regular basis," and often consults with him on climate change issues.
Could Gore serve alongside Bill Clinton in an Obama administration? Last November, the Illinois senator said he'd offer the former president a job "in a second."
"There are few more talented people [than Clinton]," Obama said then.
