The U.S. Senate will push ahead with a vote this week on a healthcare bill to repeal Obamacare, even though it was not yet clear there are enough votes for passage, NBC News reported on Tuesday, citing a comment by the chamber's No. 2 Republican.

"We expect to have the support to get it done, and yes, we will vote this week," Senate Majority Whip John Cornyn said, according to a Twitter post by NBC News.
