WASHINGTON — Testimony in the House’s first public impeachment hearing has ended, with more ahead.

A Republican lawmaker in the House impeachment inquiry into President Donald Trump says the whistleblower is the “one witness” who should be brought in front of the American people.

Rep. Jim Jordan of Ohio says the whistleblower, whose complaint touched off the inquiry, should come before the committee. He says he wants to know the identity of the whistleblower, a CIA officer assigned to the White House.

Jordan earlier complained that the witnesses Wednesday testifying publicly for the first time didn’t have firsthand knowledge of the accusations and never spoke directly to President Donald Trump.

The whistleblower has not been asked to testify.

Democratic Rep. Peter Welch of Ohio said he’d be glad to have the person who started it all testify: “President Trump is welcome to sit right there.”

Next up will be former U.S. Ambassador to Ukraine Marie Yovanovitch, who was ousted in May on Trump’s orders. She will testify Friday.

Next week, the House Intelligence Committee will hear from eight more witnesses in the impeachment probe.

State Department officials William Taylor and George Kent testified for more than five hours Wednesday about their concerns with President Donald Trump’s requests that Ukraine investigate Democrats as the U.S. withheld military aid to the country.

Democrats are investigating those requests, and whether they were linked, as they move toward an impeachment vote.

Republicans said the witnesses didn’t have firsthand knowledge and noted the aid was eventually released. The U.S. government released the money after pressure from senators in early September.
