|Donald Trump's unpredictable, pugnacious approach to the presidency often worked against him as Republicans navigated a tumultuous but ultimately productive year in Congress.
Trump's major accomplishments, confirmation of conservative Supreme Court Justice Neil Gorsuch and a major tax cut, actually came with relatively little drama. But Republicans often struggled to stay on the rails, particularly with a big pratfall on health care and repeated struggles to accomplish the very basics of governing.
Several shutdown deadlines came and went, and a default on the government's debt was averted, thanks to a momentary rapprochement with top Democrats, House Minority Leader Nancy Pelosi and Sen. Chuck Schumer. But a promised solution to the plight of young immigrants brought to the country illegally as infants or children was delayed, while a routine reauthorization of a program providing health care to 9 million low-income kids stalled as well.
Often it seemed as if Trump were more interested in picking fights on Twitter than the nuts and bolts of legislating.
A catchall spending deal in May got relatively little attention for what it accomplished, overshadowed by Trump's threat to shut the government down if he didn't get a better deal the next time. But there was no next time — and about $1.2 trillion in unfinished agency budgets got punted into the new year.
Still, there was no shortage of drama this year on Capitol Hill. Trump displayed a penchant for picking fights with fellow Republicans: Arizona's two senators John McCain and Jeff Flake; Tennessee's Bob Corker and Majority Leader Mitch McConnell of Kentucky. Onetime Republican rivals such as Sens. Ted Cruz of Texas and Lindsey Graham of South Carolina came firmly into Trump's fold — even as Corker and Flake, both facing potentially difficult primary races, announced their retirements.
