ANNAPOLIS, Md. (AP) — The White House has asked a political action committee that supports Maryland Rep. Donna Edwards’ Senate bid to pull an advertisement on gun control.

Jennifer Friedman is a spokeswoman for President Barack Obama. She said Wednesday that the Working For Us PAC was asked to pull the “misleading” ad.

It shows Obama tearing up while talking about Connecticut’s Sandy Hook Elementary School shooting. It says Rep. Chris Van Hollen supported a campaign finance disclosure bill that didn’t include the National Rifle Association. Van Hollen is running against Edwards in a competitive Democratic primary.

Van Hollen has scheduled a Wednesday news conference to call on Edwards to “stop the false attacks” on his record.

Edwards campaign spokesman Benjamin Gerdes said in an emailed statement that the campaign had “nothing to do with the ad.”
