Republicans are set to begin dismantling eight years of President Barack Obama as they take complete control of Washington and bring out the wrecking balls.

The 115th Congress will sit for the first time on Tuesday, and even before President-elect Donald Trump assumes office, Republicans on Capitol Hill are anxious to start work. Their priorities include repealing the Affordable Care Act, better known as Obamacare, a tax overhaul, the repeal of environmental regulations, a large transportation bill to create jobs, and the confirmation of a new Supreme Court justice.

 “Buckle up,” Vice President-elect Mike Pence told his former colleagues in the House last year, after meeting with them to discuss legislative plans.

“I’m very confident that as we move towards inauguration, bring together a great team, work in concert with leaders in the House and Senate, and we’re going to move an agenda that’s going to rebuild our military, revive our economy, and — in a word — make America great again.”

Indeed, with the Republicans controlling both the executive and legislative branches of government, work is likely to begin shortly after the Congress’s 59 new members — seven senators and fifty-two House members — are sworn in.
