Senate Majority Leader Mitch McConnell is facing mounting criticism from politicians and pundits on both sides of the aisle after the collapse of his chamber’s Republican health care legislation.

Before the bill was pulled Monday night, Sen. Ron Johnson told a local newspaper that McConnell’s conflicting statements to different members of his caucus were a “significant breach of trust.”

The Wisconsin Republican was referring to alleged remarks by McConnell to some GOP moderates that Medicaid cuts wouldn’t happen under the overhaul bill.

Other Republican senators are calling for a new way forward on replacing the 2010 health care law. Sen. Jerry Moran, one of four GOP senators whose decision to oppose the health care legislation contributed to its dismantling, criticized the “closed-door process” that McConnell used to draft the bill.

“We must now start fresh with an open legislative process,” the Kansas Republican said in a statement Monday night.
