WASHINGTON (Reuters) - John Boehner narrowly won a third term as House of Representatives speaker on Tuesday, surviving a stiff challenge from 25 conservative Republicans as the party took full control of Congress.
Boehner received 216 of 408 votes cast in a tense vote, with a growing faction of dissident House Republicans declining to vote for him and nearly depriving him of a majority.
The group of Republican defectors was more than twice the dozen who withheld their support from him in an election two years ago, in an indication of stark party divisions that could make it hard to pass legislation.
Boehner can afford to lose a few more Republican votes on tough legislation after November elections gave the party its largest House majority since 1947. But with Tuesday's vote indicating a more restive right flank, he may need to depend even more on Democrats to win close votes.
"As speaker all I ask and frankly expect is that we disagree without being disagreeable, in turn I pledge to help each of you carry out your duty," a tearful Boehner told House members after the election. "My door, of course, is always open."
A core group of conservatives had campaigned against Boehner, arguing he had done too little to cut spending and fight President Barack Obama's immigration and healthcare policies.
Representative Justin Amash said on his Facebook page that the House needs "modern" leaders with limited terms.
"Speaker Boehner has given his best to our conference, and I thank him for his service. But it's time for Republicans to change our leadership. This afternoon, I will vote for a new speaker," Amash wrote.
The conservatives were particularly angry about Boehner's handling of a $1.1 trillion spending bill in December. They say the 1,600-page measure was negotiated in secret and failed to deny funds to agencies responsible for implementing Obama's executive immigration order, which lifts the threat of deportation for millions of undocumented immigrants.
Late on Monday, Republicans briefly discussed the possibility of attaching language to the DHS funding bill that would withhold any federal funds for the department's employees to implement Obama's order, according to Representative John Fleming of Louisiana.
Such a move is likely to draw a veto from Obama, threatening operations of one of the most important federal agencies in the post-Sept. 11, 2011 era.
Republican Senator Mitch McConnell, who assumes the Senate majority leader job on Tuesday and has been hoping to avoid any government shutdown fights this year, could temper such House legislation and force Boehner's Republicans to compromise.
McConnell has influence over the House because the Senate will need to approve any legislation for it to win final passage.
But even some of the most conservative House members also were expressing the need to ease their hard-line stances.
"It might be that I end up voting for some things that are not clear victories but they are somewhat victories. But that's what the legislative process is about," said Fleming, who helped orchestrate the 2013 federal government shutdown in a failed attempt to kill Obamacare.
Republicans still may not be able to achieve a full repeal of Obama's signature health care law, but they are expected to chip away at it by passing measures to ease requirements for employer health care coverage and repeal an excise tax on medical devices. On the energy front, the first major bill the Republican-controlled Senate intends to pass is approval of the Canada-to-Texas Keystone XL oil pipeline.
Another big test of McConnell's leadership is likely to come by mid-year, when Congress will either have to raise the government's borrowing authority or risk a credit default. The debt limit fight is always a hot-button issue for conservatives who oppose more borrowing.
