House Speaker Nancy Pelosi, who is traveling in Europe with a congressional delegation, deflected direct criticism of President Trump during an event at the London School of Economics and Political Science.

The school’s director of the U.S. Center, Peter Trubowitz, asked Pelosi if the GOP and Trump were conducting their bid to win in 2020 “like a debate about extremisms,” by labeling Democrats a party that endorses socialism while Republicans govern to the right.

“I don’t criticize the president outside the country,” Pelosi, D-Calif., shot back.

Pelosi wouldn’t talk about Trump politically or personally, which she does frequently in the United States. But she criticized his decision to impose tariffs on the European Union rather than pairing with the EU to extract trade concessions out of China.

“I was not pleased when the president put tariffs on the EU and weakened that strength that could have been there vis a vis China,” Pelosi said. “The Chinese enjoyed that a lot.”

She then criticized Trump, without naming him, over his tweet attacking Rep. Ilhan Omar, D-Minn., that used a video of the flaming twin towers on Sept. 11.

"I would say I don't think any president of the United States should use the tragedy of the United States as a political tool," Pelosi said. "I think it's wrong. It's beneath the dignity of the office and I don't think it plays very well."

Pelosi is traveling with a congressional delegation in Europe while the House is in recess this week.
