House Majority Whip Jim Clyburn said Sunday that there is a “possibility” the vote on a bipartisan infrastructure package will be delayed, despite Democratic House leaders promising moderate members a vote by September 27.

“There’s always a possibility that the vote would get delayed, but the question is, ‘Are we going to work to get to our goal for September 27?’ Yes, we’re going to work hard to reach that goal, and sometimes you have to kind of stop the clock to get to the goal. We’ll do what’s necessary to get there,” Clyburn, the third-ranking House Democrat, told CNN’s Jake Tapper on “State of the Union.”
