WASHINGTON (Reuters) - U.S. Senate Minority Leader Chuck Schumer said Sunday that senior administration officials must testify in President Trump's impeachment trial after a report that Trump told a former aide to hold up military aid to Ukraine pending investigations into political rivals.

In a tweet, Schumer said Republicans must back efforts to call former national security adviser John Bolton, among others, to testify.
