The Senate will take up a House-passed bill to repeal and replace Obamacare next week, despite significant opposition from Republican lawmakers, Senate Majority Leader Mitch McConnell said.

"We are not slowing down," McConnell, R-Ky., told reporters after a closed-door meeting with the Senate GOP on Tuesday. "We are going forward."

McConnell said if the House is able to pass the bill this week, he will take the measure directly to the Senate floor for consideration, bypassing several committees.

McConnell said he has no plans to postpone consideration of the healthcare bill beyond next week because he will bring to the floor the nomination of Supreme Court pick Neil Gorsuch the week of April 3.

The Senate will leave town for a two-week recess on April 7.

The Senate could, in theory, move quickly on the healthcare bill because it will use a budgetary tool that will require only 51 votes to pass it rather than the usual 60 votes.

But Republicans, who hold a 52-seat majority, are hardly unified behind the plan.

Several Republican senators have already voiced opposition to the proposal in current form.

McConnell said lawmakers could change the bill during the amendment process.

"We will have opportunities to modify the proposal," McConnell said. "We'll be listening to everybody, all in an effort to get enough votes to clear the Senate."

If the Senate alters the bill, it would require passage, once again, in the House before it could clear Congress for President Trump's signature.
