Starting today, House investigators will question witnesses in the impeachment inquiry against President Donald Trump on live television — and both parties have prepared competing messages about Trump's conduct for the historic event. First up will be William Taylor, the acting U.S. ambassador to Ukraine, and George Kent, the State Department's top Ukraine official. Both men have already described a White House effort to pressure Kyiv into providing political favors for Trump.
How will this measure up to previous proceedings? Observers say the public mood is far more polarized than during the hearings against ex-Presidents Richard Nixon and Bill Clinton.
