A group of nearly a dozen mayors from across the country met with White House officials on Monday in an effort to push the president towards supporting a universal background check bill, including Pittsburgh Mayor Bill Peduto, who’s currently involved in a lawsuit over Pittsburgh’s newly enacted gun control ordinances. The mayors didn’t meet with President Trump personally, but were involved in discussions with White House staff.

Rochester Hills, Mich., Mayor Bryan Barnett (R), who also serves as president of the United States Conference of Mayors, told Axios that it is no longer a shock when one hears that a mass shooting occurred “because it’s happening with such regularity.”

“I think we are seeing a tipping point,” Barnett said. “I’ve seen a change here. While they’re not looking to go as far as some folks on the left want to go, they understand something needs to be done. The status quo really isn’t acceptable.”

Meanwhile, a pair of anti-gun senators say they expect White House staffers to brief Trump on a potential gun control plan as early as Wednesday of this week.

Sen. Joe Manchin (D-W.Va.) said White House staff told him they would take a potential gun control plan to Trump this week, likely on Wednesday, and brief him on the status of negotiations.

“They told me … that they hoped to get something, a draft of something they thought would be acceptable to present to him,” Manchin told reporters. “I think that he will start looking at what recommendations they’ve finally come to.”

Sen. Chris Murphy (D-Conn.), asked about Manchin’s timeline, said White House staff have told him they intend to brief Trump this week, adding, “At this point, I think the president probably needs to make a decision.”

“What they’ve told me is this week,” he said. “I think they’re at the point where they need to bring the status of negotiations to the president and make some decisions. We’ve made some offers. We’ve put some creative ideas on the table so we’re not coming in and saying universal background checks only or Manchin-Toomey only.”

Asked Monday when he will release his plan to address gun violence, Trump said: “We’re dealing with Democrats. We’re dealing with Republicans. We’re talking about a lot of different things having to do with, as you call it, gun control.”

At the same time, he said, “we have to protect our Second Amendment very strongly and we will always do that.”
