“This is your fault,” Sen. Ron Johnson (R-Wis.) told Majority Leader Mitch McConnell (R-Ky.) at one point, according to two Republicans who attended the lunch and witnessed the exchange.

“Are you suggesting I’m enjoying this?” McConnell snapped back, according to the people who attended the lunch…

Six Republicans broke ranks to vote for the Democratic plan, which would have reopened shuttered government agencies through Feb. 8, without any wall money. Among them was Sen. Mitt Romney (R-Utah), who explained in the lunch why he planned to vote for both bills.

Sen. Thom Tillis (R-N.C.), who voted for Trump’s bill but opposed the Democratic plan, started to interrupt him and Romney snapped back, according to one of the people who attended the lunch and another person familiar with it. The exchange was lively but not particularly angry, they said.
