(CNN) — A top-ranking Republican on one of the most influential committees in Congress announced Friday that he plans to resign — opening up yet another G.O.P. seat in a year that has already seen 18 Republicans announce plans to leave the chamber.

Jim McCrery, of Louisiana, said at a news conference late Friday that he does not intend to seek re-election to the House next year. McCrery, currently serving his 10th full term, is the ranking Republican on the powerful House Ways and Means Committee and was in line to chair the committee before Democrats took control in the 2006 elections.

"Congressman Jim McCrery has distinguished himself in Congress as a key player in the debate of some of the most pressing issues facing our country," said Tom Cole, chairman of the National Republican Congressional Committee. "He has been a champion for the American taxpayer and his work on issues like retirement security and health care has also earned him a great deal of respect from members of Congress on both sides of the aisle."

Romney and Giuliani tussled over immigration at the beginning of the debate.

WASHINGTON (CNN) — In the first moments of the CNN/YouTube debate, sparks flew between former New York City Mayor Rudy Giuliani and former Massachusetts Gov. Mitt Romney on the issue of so-called sanctuary cities for illegal immigrants.

After Romney attacked Giuliani for saying New York was not a sanctuary city, Giuliani responded by saying Romney lived in a "sanctuary mansion" and that Romney employed illegal immigrants at his own home.

Romney denied the allegations.

Watch the candidates debate immigration.

(CNN) – Former Sen. Fred Thompson of Tennessee jumped into the immigration showdown with former New York Mayor Rudy Giuliani and former Massachusetts Gov. Mitt Romney, saying that although immigrants are part of what makes the United States a great nation, "It's our home. We now get to decide who comes into our home. To place somebody above [those waiting for legal immigration] or in front of them in line is the wrong thing to do."

Thompson said federal funding should be cut off to cities that provide sanctuary to illegal immigrants.

Thompson also took a jab at Giuliani, who bashed Romney for employing illegal immigrants, and defended his own record of employee scandals.

"I think we've all had people probably that we've hired that in retrospect probably was a bad decision," Thompson said, referring to a campaign fundraiser and personal friend who resigned from the Thompson campaign because of drug-related crimes and issues with the IRS.

Mitt Romney of Massachusetts and former New York City Mayor Rudy Giuliani. In response to a question about immigration, Thompson accused Romney of supporting President George W. Bush's failed immigration reform plan, and then shifting positons. He then joined Romney in going after Giuliani by also labeling New York a sanctuary city while Giuliani was mayor.

Former Bush speech writer Michael Gerson is concerned about immigration and poverty.

WASHINGTON (CNN) – Former Bush speech writer and book author Michael Gerson visited the Situation Room this week. Gerson spoke with Suzanne Malveaux about what he thinks in wrong with his party.

“Republicans can’t just talk about budgets. They have to talk about people,” Gerson told Malveaux. “Eventually, you need that message,” he added.

Gerson believes the Republican Party ought to do more to address poverty and “populist economic issues.” He also tells Malveaux that the GOP is making a mistake in blocking comprehensive immigration reform. The “Republican leadership of the Congress is actively alienating the fastest growing group of voters in America,” explained Gerson, referring to the country’s growing Latino population.

DES MOINES, Iowa (CNN) — In some polls, immigration ranks behind only the Iraq war and the economy as Iowa voters' top issue.

A recent University of Iowa poll found that 58 percent of Republican voters consider the issue very important.

Republican candidates are trying to convince those voters that they are the ones to fix immigration as they head into the nation's first contest in the presidential primary season.

Iowa's meatpacking industry has become a magnet for illegal immigrants and the impact on taxpayers regularly makes headlines.

Iowa Republicans say the issue can make or break a campaign.

Sen. Clinton launched a new ad Tuesday.

NEW YORK (CNN) – Sen. Hillary Clinton, D-New York, tells New Hampshire voters she’s the only candidate that can beat the “Republican attack machine” in a new television campaign ad that began running Tuesday in the Granite State.

“Here they go again — the same old Republican attack machine is back,” an announcer says in the ad. “Why? “Maybe it’s because they know that there’s one candidate with the strength and experience to get us out of Iraq.”

Clinton has portrayed herself as the most electable candidate in the Democratic field, and recent polling in the Granite State indicates that a majority of Democratic voters agree. According to a recent CBS News-New York Times poll, 68 percent of likely New Hampshire Democratic voters said they thought Clinton has the best chance of winning the general election.

RNC Spokesman Brian Walton criticized Clinton for the ad and said she holds political rivals responsible for her problems.

“Throughout her career Senator Clinton has time and time again blamed political opponents for her problems,” Walton said. “With Senator Clinton’s campaign in freefall it is no surprise that she would resort to the same tired excuses.”

WASHINGTON (CNN) – New Jersey Rep. Mike Ferguson announced Monday he would not seek reelection in 2009, the 18th Republican this year to announce plans to either leave office during or retire at the close of the 110th Congress.

Ferguson, who was first elected in 2000, narrowly won re-election last year beating Democrat Linda Stender by a 49 percent to 48 percent margin.

Ferguson said he decided to leave Congress so that he could spend more time with his family.

“Being a representative in Congress is more meaningful than I had imagined, and I know that now is the right time to step away from public life to focus more on family life while our children are still young,” he said in a statement released by his congressional office.

WASHINGTON (CNN) — Citing health reasons, Rep James Saxton, R-N.J., announced Friday he plans to retire at the end of his term.

"Although I had intended to run in 2008 and was planning a strong campaign, developments which occurred earlier this year regarding my health have prompted me to make this decision," Saxton said in a written statement. He has been treated for prostate cancer.
