President Trump is said to have frozen aid

Two senior administration officials told The Times that Mr. Trump ordered the suspension of about $391 million for Ukraine shortly before a July phone call in which he’s said to have encouraged the country’s president to investigate Joe Biden.

Democratic leaders are demanding that the administration turn over documents involving the matter.

Mr. Trump denied on Monday that he had withheld aid to press for an investigation, but he also suggested that there wouldn’t have been anything wrong with doing so.

The details: Congressional Democrats have said that pressuring a foreign government for dirt on a political rival could be an impeachable offense regardless of whether American aid was involved. Here’s where every House member stands on an impeachment inquiry.

What’s next: Speaker Nancy Pelosi plans to meet today with the leaders of six House committees that are investigating Mr. Trump and will later discuss impeachment with the full Democratic caucus.

News analysis: Our senior White House correspondent writes of Mr. Trump: “The last time he was accused of collaborating with a foreign power to influence an election, he denied it and traveled the country practically chanting, ‘No collusion!’ This time, he is saying, in effect, so what if I did?”
