WASHINGTON (AP) — President Donald Trump on Tuesday came under growing pressure to respond to allegations that Russia offered bounties for killing American troops in Afghanistan, with Democrats demanding answers and accusing Trump of bowing to Russian President Vladimir Putin at the risk of U.S. soldiers’ lives.

Frustrated House Democrats returning from a briefing at the White House said they learned nothing new about American intelligence assessments that suggested Russia was making overtures to militants as the U.S. and the Taliban held talks to end the conflict in Afghanistan. Senate Republicans who attended a separate briefing largely defended the president, arguing along with the White House that the intelligence was unverified.

The intelligence assessments were first reported by The New York Times, then confirmed to The Associated Press by American intelligence officials and others with knowledge of the matter.

White House press secretary Kayleigh McEnany said Tuesday that Trump had been briefed on the intelligence, a day after saying he hadn’t because it had not been verified. McEnany added that there were still reservations within the intelligence community on the veracity of the allegations.

“Make no mistake. This president will always protect American troops,” she said.

Majority Leader Steny Hoyer and a small group of other House Democrats met with White House officials as Trump downplayed the allegations. The Democrats questioned why Trump wouldn’t have been briefed sooner and pushed White House officials to have the president make a strong statement about the matter.

House Intelligence Committee Chairman Adam Schiff, one of the Democrats who attended the briefing, said it was “inexplicable” why Trump won’t say publicly that he is working to get to the bottom of the issue and why he won’t call out Putin. He said Trump’s defense that he hadn’t been briefed was inexcusable.

“Many of us do not understand his affinity for that autocratic ruler who means our nation ill,” Schiff said.

Rep. Mikie Sherrill, D-N.J., a freshman and former Navy helicopter pilot and Russia policy officer, said White House chief of staff Mark Meadows briefed the group. She said the Democrats told the White House briefers that the president should make a statement.

“These are very concerning allegations and if they’re true, Russia is going to face repercussions,” Sherrill said. “We really pushed that strongly in the meeting.”

She wouldn’t say how the White House officials reacted or say if the briefers told the Democrats that in fact Trump had been briefed.

Trump and his aides set a high bar for briefing a president since it is rare for intelligence to be confirmed without a shadow of doubt before it is presented to senior government decision-makers.

McEnany declined to say why a different standard of confidence in the intelligence might apply to briefing lawmakers than for bringing information to the president.

Some House Republicans who were briefed by the White House on Monday also said they left with questions.
