Speaker Nancy Pelosi was visibly appalled at much of President Donald Trump’s State of the Union address Tuesday night, but there was one particular line that seemed to be bugging her the next morning: “If there is going to be peace and legislation, there cannot be war and investigation.”

“It was a threat. It was an all-out threat,” the California Democrat told reporters Wednesday morning.

“The president should not bring threats to the floor of the House,” Pelosi said. “He said he wasn’t going to cooperate unless we didn’t exercise our constitutional responsibility to oversight.”

And that’s what it is, she emphasized. “It’s not investigations. It’s oversight.”
