For the first time in front of live cameras, US lawmakers have had the opportunity to question witnesses in the impeachment hearing of Donald Trump.
Acting US Ambassador to Ukraine William Taylor and State Department official George Kent both described an "irregular" channel led by Trump allies to pressure Ukraine to investigate the Bidens in exchange for a White House meeting and US military aid.
Taylor described how one of his assistants overheard a call between US Ambassador to the EU Gordon Sondland in which Trump said he did not care about Ukraine and just wanted the country to probe the Bidens. The existence of this call between Trump and Sondland had not been previously disclosed in earlier testimony. In a White House press conference later, Trump disavows any knowledge of such a call.
On Friday, recalled US Ambassador to Ukraine Marie Yovanovitch will take the stand for phase two of the televised impeachment hearings.
