Acting White House Chief of Staff Mick Mulvaney on Sunday said no politician — including President Trump — can be blamed for the mass shootings over the weekend that killed 29 people, saying responsibility for the atrocities belong to the gunmen.

“This is a serious problem, no question about it, but these are sick, sick people and the president knows it,” Mulvaney said on ABC’s “This Week.” “But I don’t think it’s fair to lay this at the feet of the president.”

Mulvaney said the screed posted online by the shooter in Saturday’s carnage in El Paso, Texas, shows that he had been expressing his hate-filled views before Trump entered the White House.

“This was a sick person. The person in Dayton was a sick person. No politician is to blame for that,” he said. “The people responsible here are the people who pulled the trigger.”

Officials in El Paso said the shooter, who killed 20 people and wounded 26, shows a possible “nexus to a hate crime” by his extreme views.

ABC’s Jonathan Karl raised Trump’s lukewarm response when asked in March whether he thought the spread of white nationalism around the world was a problem.

Trump answered that he thought it was confined to a “small group of people who have a very, very serious problem.”

“There’s no benefit here to trying to make this a political issue,” Mulvaney said. “This is a social issue.”

He said some people think the president was happy about the mass shootings that killed 20 in El Paso and nine in Dayton.

“That’s a sad, sad state of this nation,” Mulvaney said. “He’s angry. He’s upset. He wants it to stop.”
