Senate impeachment trial: Wednesday acquittal vote expected after effort to have witnesses fails

(CNN)The Senate on Friday voted to block any witnesses from being called in President Donald Trump's impeachment trial, a move that marked the beginning of the end of the third Senate trial for a president in US history.

The timing for the final acquittal vote was a subject of debate throughout the day on Friday, but Republican senators leaving a meeting Friday evening said that it was likely to occur on Wednesday -- after Trump's State of the Union address on Tuesday.
