On Wednesday, Democrats in the U.S. House of Representatives began holding public impeachment hearings on the president. Democrats said Trump threatened to withhold military aid to Ukraine unless the foreign government investigated Hunter Biden, the son of former Vice President Joe Biden.
Republicans say the impeachment hearings are a one-sided political stunt and the Democrats' latest attempt to oust Trump from office.
There are still more than a dozen Democrats running to oppose Trump next year, but only a few remaining, serious contenders. They include Biden, and U.S. Sens. Elizabeth Warren and Bernie Sanders. U.S. Sen. Kamala Harris' campaign is downsizing and pinning all its hopes on next year's Iowa caucus.
At least 10 candidates will be in Atlanta on Nov. 20 for the fifth Democratic debate. The debate will be at Tyler Perry Studios, a 330-acre film and production company founded by the Atlanta-born entertainment mogul.
