Senate vote on proposal to block EPA climate rules slated for Wednesday

The timing for the vote on the amendments has been something of a moving target. Lawmakers told The Hill Monday night that the path forward on the amendments was unclear.

It’s highly unlikely that McConnell’s amendment will garner the 60 votes necessary for passage. But a vote on the amendment would force moderate Democrats facing tough reelection bids to weigh in on the issue.

The two amendments from Democrats face major hurdles as well.
