President Trump at a Monday night rally claimed House Speaker Nancy Pelosi was “mumbling terribly” behind him at last week’s State of the Union address — leading the New Hampshire crowd to chant “lock her up.”

“That was very distracting,” the president told his supporters at the SNHU Arena in Manchester of Pelosi’s supposed interruption from the House chambers’ dais.

“I’m speaking and a woman is mumbling terribly behind me. Angry, there was a little anger back there,” the president said. “We’re the ones who should be angry.”

Trump’s remarks ignited the “lock her up” chant that became a popular rally cry four years ago whenever the president mentioned his 2016 Democratic challenger, former secretary of state Hillary Clinton.

The bad blood between Trump and Pelosi seemed to reach a boiling point last Tuesday at the State of Union address, with the two trading shots.

The president, before beginning his speech, refused to shake Pelosi’s hand. After the address, the House speaker ripped up a copy of Trump’s speech.

Trump’s Monday rally came a day ahead of the New Hampshire primary, where independent or undeclared voters can participate in either party’s contest.

The president speculated the setup may help Republicans sway the results.

“I hear a lot of Republicans tomorrow will vote for the weakest candidate possible of the Democrats,” Trump told the crowd.

“My only problem is I’m trying to figure out who is the weakest candidate. I think they’re all weak.”
