Collins stated that the reason for now being the time for action is there were 3 incidents so close together. This includes the incident in Philadelphia.
Sen. Susan Collins, R-Maine, appeared on "The Story with Martha MacCallum" on Thursday and said she was working on bipartisan legislation to close "loopholes" in the background check system. She made the case for Democrats and Republicans finding common ground on gun control.
"If we can come together working with President Trump working with colleagues from both sides of the aisle and say that if you advertise the sale of a firearm over the Internet there should be a background check, that makes sense to me," Collins said.
The senator said she wouldn't support the recent House bill -- calling it an overreach -- but did say that background checks were something to unite around.
"I'm working with Sen. Pat Toomey and Joe Manchin and with the White House on making sure that we close some loopholes in the background check system to ensure that people with criminal records or who are mentally ill can not purchase firearms," she said.
