Envoy to Ukraine describes quid pro quo

Multiple senior administration officials said that President Trump had blocked military aid to Ukraine until the country’s leader agreed to investigate Mr. Trump’s political rivals, according to testimony on Tuesday by the top American diplomat in Kiev.

The envoy, William Taylor, told House investigators in detail about an arrangement that Mr. Trump and his allies have long denied. Read Mr. Taylor’s opening statement and six revelations from his testimony.

Before Mr. Taylor’s appearance in Congress, the president denounced the investigation as a “lynching.”

News analysis: The testimony by Mr. Taylor was “by far the most damning account yet to become public” in the impeachment inquiry, our chief White House correspondent writes.
