Watch Jessica Yellin's report on a new report by Congressional Democrats.
WASHINGTON (CNN) - Democratic leaders in Congress released a report Tuesday where they estimated the total costs of the country's military operations in Iraq and Afghanistan.
The report estimates the total cost of the war on terror– including what Democrats call the war's "hidden costs" - at $1.6 trillion.
This is twice what President Bush has requested from Congress to fund operations in Iraq and Afghanistan but far less than the $50 billion the Bush administration initially estimated for the Iraq war in 2003.

Watch Tancredo defend his controversial ad in an interview with CNN's Wolf Blitzer .
WASHINGTON (CNN) - Republican presidential candidate Rep. Tom Tancredo is standing by his new television ad depicting a terrorist attack on an American mall, saying it portrays a real threat.
"Yes, they are coming, they are coming through our porous borders, and yes, they are coming to do us great damage," the Colorado Republican told CNN's Wolf Blitzer on Tuesday. "I don't know why anybody would not think this is true."
The 30-second ad, set to begin running on Iowa cable stations this week, depicts a hooded man walking into a crowded mall with a backpack. Over the sound of a ticking clock, the man abandons the backpack at a bench, and an explosion is heard.
"There are consequences to open borders beyond the 20 million aliens who have come to take our jobs," the ad's narrator says. "Islamic terrorists now freely roam U.S. soil. Jihadists, who froth with hate, here to do as they have in London, Spain and Russia."

Edwards is out with a new ad Tuesday.
WASHINGTON (CNN) – New York Sen. Hillary Clinton's presidential campaign called a new television ad released Tuesday by former North Carolina Sen. John Edwards "unconstitutional gimmickry."
In the commercial airing in Iowa, Edwards promised to end congressional health care benefits if they fail to pass a universal health care plan within six months of his administration.
"There’s no excuse for politicians in Washington having health care when you don’t have health care," Edwards said in the ad.
But Clinton's campaign pointed out on its Web site that this proposal is unconstitutional. The Clinton campaign said it would violate the 27th amendment, which states that any law to change the compensation of members of Congress has to be approved by the House.
Rep. Barney Frank endorsed Clinton Tuesday.
WASHINGTON (CNN) - Rep. Barney Frank, D-Massachusetts, endorsed Sen. Hillary Clinton for president Tuesday, and will serve as an economic adviser to the New York Democrat.
“I am particularly pleased by her commitment to reverse the economic policies that have created a situation in which as the country progresses economically, only a small number of Americans benefit,” Frank, who chairs the House Financial Services Committee, said in a statement released by the campaign.
The openly gay Massachusetts Democrat also praised Clinton’s positions on social issues.
“Based on my work with her on issues involving discrimination, I am convinced that Hillary Clinton is the best candidate best equipped to pass laws that will treat all Americans with dignity and equality no matter who they are or who they love,” said Frank.

Dodd scored a key endorsement in Iowa Tuesday.
WASHINGTON (CNN) – Presidential hopeful Chris Dodd Tuesday won the support of a key Iowa Democrat.
Terry Stewart, the chairman of the Dubuque County Democratic Party, hailed the Connecticut senator as "uniquely qualified to be president," and cited Dodd’s legislative successes in the Senate as the chief reason he is offering his support.
"I didn't come to this decision lightly," Stewart said in remarks circulated by Dodd's campaign. "I studied the range of Democratic candidates this entire calendar year...I looked for the edge that one candidate would have over the others. Chris Dodd rose to the top of the roster."
Romney was critical of his rivals from both parties Tuesday.
SIOUX CITY, Iowa (CNN) – Republican presidential hopeful Mitt Romney took shots at his GOP and Democratic rivals Tuesday, accusing several of them of being soft on illegal immigration.
"There's a sanctuary state of mind that [New York Sen.] Hillary Clinton, and [former New York City] Mayor Giuliani, and [former Arkansas] Gov. Huckabee have," Romney said at a news conference. "They have provided - or support the idea of providing - tuition breaks to illegal aliens to institutions of higher learning, and that sanctuary state of mind flies in the face of the rule of law."
Clinton is seeking the Democratic presidential nomination, while Giuliani and Huckabee are challenging Romney for the GOP presidential nomination.
A Giuliani campaign spokeswoman fired back, and criticized Romney for his own track record on the issue of illegal immigration.
"Once again Presidential Trail Mitt Romney completely ignores the record of Governor Mitt Romney," Maria Comella, Giuliani's deputy communications, said in an email statement. "Under Governor Mitt Romney the number of illegal immigrants skyrocketed, while he recommended millions of dollars in state aid to numerous sanctuary cities and to companies employing illegal immigrants, not to mention the illegals working on his own lawn."

GOP presidential hopeful Fred Thompson campaigns Monday in Oskaloosa, Iowa.
WASHINGTON (CNN) - The National Right to Life Committee, a key anti-abortion group, endorsed Fred Thompson for president Tuesday, saying the former senator was the best candidate to beat Republican front-runner Rudy Giuliani.
Thompson trails Giuliani, a former New York mayor who supports abortion rights, in the race for the Republican presidential nomination, according to most national polls.
National Right to Life Executive Director David O'Steen suggested that Giuliani's lead played a part in the committee's decision to endorse Thompson.
