Romney and Trump shook hands at the White House lunch Thursday, and Romney said there didn’t appear to be any signs of lingering tension between the two of them, even though Trump slammed the senator last month as a “pompous ass.”

Trump even invited Romney to play a role in an effort to curb vaping products, which Trump has elevated as one of his priorities.

“It was a very delightful meeting with the president and vice president and senior members of his staff and several Republican senators. We were able to talk about vaping and considered various options, and each of us spoke about our thoughts in that regard,” Romney told reporters after the meeting.

Asked if he or the president acknowledged any of the past tension in their relationship, Romney simply said, “nope” and added, “yes, of course” when asked if he shook Trump’s hand.

“We’re friendly and cordial,” he said.

Romney shrugged off Trump tweeting last month that “he is a pompous ‘ass’ who has been fighting me from the beginning.”

“That’s as accurate as it is irrelevant,” Romney joked to reporters who asked him about that pointed comment from Trump.

Thursday’s lunchtime discussion at the White House was mainly focused on legislation to lower prescription drug costs. Trump also discussed with senators the prospect of the U.S.-Mexico-Canada Agreement (USMCA) trade deal.

“We did have a discussion about USMCA. He obviously has a desire to get that passed,” Romney confirmed, adding that Trump offered no comment about the prospects of an imminent deal with Speaker Nancy Pelosi Nancy PelosiDemocratic senator to party: 'A little message discipline wouldn't kill us' Overnight Health Care: New wave of COVID-19 cases builds in US | Florida to lift all coronavirus restrictions on restaurants, bars | Trump stirs questions with 0 drug coupon plan Overnight Defense: Appeals court revives House lawsuit against military funding for border wall | Dems push for limits on transferring military gear to police | Lawmakers ask for IG probe into Pentagon's use of COVID-19 funds MORE (D-Calif.) to move the stalled trade pact.

Trump opened the meeting with a brief discussion about the House impeachment proceedings but GOP senators who were in the room said it wasn’t anything he hasn’t already said in public.

The president and senators also discussed recent Republican losses in Kentucky and Louisiana, where Republicans lost gubernatorial races.

Trump courteously listened to Romney’s ideas on curbing vaping products, an issue that has become prominent since the vaping-related deaths of nearly 50 people and illnesses affecting more than 2,000 people this year.

“I expressed my point of view, which is that I thought that there is a great deal of support for removing, if you will, the candy flavors. And while there may not be a lot of support for removing the menthol flavor, then I hope we can make progress on those places where there is general support,” Romney said.

The lawmaker from Utah told Trump that he hoped that the Food and Drug Administration would take action to regulate vaping products while Congress considers legislation.

Trump then invited Romney and other senators to provide information to his advisers on the issue.
