Several Republicans have come out Monday against the current measure to repeal and replace Obamacare, bringing CNN’s whip count to 21 Republicans — mostly moderates — opposed to the bill with at least 17 lawmakers still undecided.

There is no vote scheduled and it’s unclear if there will be one before the House leaves for a week-long break Friday. There is a lot of talk and significant pressure from the Trump administration to act — Vice President Mike Pence, who has been working with congressional leaders from the start on the health care effort, headed to Capitol Hill as well to lobby lawmakers.

Pence will spend much of Tuesday on Capitol Hill as well. He will meet with Senate Republicans for lunch, then meet with lawmakers during the afternoon.
