But continuing GOP divisions, a lack of clear leadership and some recent high-profile scandals are already distracting from the party's ambitious policy agenda.
First up, possibly this week, will be House votes to approve the controversial Keystone XL pipeline, followed later by moves to undo Obama's
Without a clear Republican presidential front-runner to guide the way, it will fall to House Speaker
First Boehner must clear his own reelection as speaker Tuesday. Though a small number of Republicans have signaled displeasure with Boehner as party leader — rekindling memories of conservatives' failed coup two years ago to oust the speaker — Boehner is expected to retain his hold on power.
But despite expectations that he and McConnell would move swiftly to show Americans that a GOP-led Congress can govern effectively, it remains unclear how the leaders will proceed. As of Friday, the House schedule for the opening week was still not set.
That stands in contrast to the "100 hour" agenda promised by then-House Speaker
Republican priorities will probably come into sharper focus later this month during a private out-of-state retreat to map the agenda for the year ahead. It is the first time in recent years that all Republicans from both chambers will huddle to plot strategy.
"The new American Congress will bring us an opportunity to begin anew, and as Sen. McConnell and I have pledged, the people's priorities will be our priorities," Boehner said recently. "We've also made clear that early on, we'll make a direct challenge to the president's unilateral actions on immigration."
The difficult part will be finding a middle ground inside the Republican Party. On a series of issues, including immigration and tax reform, party leaders must bridge the divide between
Democrats are already dismissing Boehner's "new American Congress," pointing to recent headline-grabbing controversies that they say evoke familiar negative stereotypes about Republican thinking on minorities and women.
The No. 3 House Republican, Rep.
"It was a mistake I regret," Scalise said of his appearance before the European American Unity and Rights Organization, labeled a hate group by the Southern Poverty Law Center. "And I emphatically oppose the divisive racial and religious views groups like these hold."
Around the same time, New York Republican Rep.
"The congressman will not let the outrageous claims of a disgruntled former employee interfere with his representing the people of Texas," spokesman Kurt Bardella said in an email late last week. "He plans to continue to fight for lower taxes, more and better jobs and a smaller government."
Like Grimm, the Corpus Christi-area congressman, elected in the 2010 tea party wave, won reelection last fall despite an opponent's ad that recycled an earlier photo of him wearing pajamas with a scantily-clad woman.
"Republicans are off to a banner start for their new Congress," quipped a recent missive from the Democratic Congressional Campaign Committee, predicting they were "on the path to break their own record for least popular Congress in history."
To be sure, Democrats have their own hurdles ahead as the party's progressive wing, increasingly led by Sen.
Divisions between the White House and Democrats on Capitol Hill came into stark focus after the damaging midterm election, when each blamed the other for the party's losses.
Liberal Democrats have little interest in Obama's effort to work with the GOP to approve a far-reaching trans-Pacific trade agreement with Asian nations, which they say will cost American jobs. Neither do progressives back his pursuit of corporate tax cuts that they warn would deprive the government of needed revenue. But as the minority party now in both houses, Democrats' role has diminished.
For Republicans, their performance in the coming months will become a referendum not only on their ability to lead — a key question in the 2016 presidential race — but on what has become the party's increasingly conservative ideology.
The incoming House Budget Chairman, Rep.
With the first Republican congressional majority since 2006, social conservatives are expected to push for legislation to curtail abortions and limit same-sex marriage, though such bills would probably be blocked by Democratic filibusters in the Senate or presidential vetoes.
One early battle will come next month when Congress must renew funding for the Homeland Security Department. Though other government operations have been funded until September, Republicans agreed to only a short-term extension for Homeland Security, which oversees immigration agencies, as a protest against Obama's plan to defer deportation for up to 5 million people living in the U.S. illegally.
To minimize the infighting, Boehner's team is hoping to start this week with an easy legislative lift: a modest bipartisan bill to encourage small businesses to hire military veterans.
But in a volley to Obama, the bill does so by making a tweak to the Affordable Care Act, the first of what will probably be many attempts by the GOP-led Congress to scale back the president's signature program.
