Trump impeachment: Major blow for Democrats in witnesses battle

US democrats were dealt a major blow in their efforts to call witnesses at president Trump’s impeachment trial.

They needed four republicans to vote with them to allow witness testimony, but one of the few wavering senators said he would not support the measure.

Lamar alexander said the democrats had proved that Trump acted inappropriately but it was not an impeachable offence.

The announcement paves the way for the possible acquittal of the president by the senate as early as Friday.
