WATCH: Nunes says Yovanovitch is not ‘a material fact witness’ in impeachment probe

The top Republican on the House Intelligence Committee is arguing that former U.S. Ambassador Marie Yovanovitch “is not a material fact witness” in the House impeachment probe of President Donald Trump.

Rep. Devin Nunes spoke on Nov. 15 as part of the impeachment hearings into President Donald Trump. Watch in the player above.

California Rep. Devin Nunes said the details of her May ouster at Trump’s direction are a human resources issue, instead of a matter relevant to the Democrat-led investigation.

Democrats are investigating Trump’s dealings with Ukraine and his direct appeals to the country to investigate Democrats. They say Yovanovitch’s dismissal set the stage for a separate policy channel lead by Trump’s lawyer, Rudy Giuliani. Giuliani pushed for her firing.

Nunes noted that she had not talked to Trump this year or been part of preparations for a July phone call in which Trump asked the Ukrainian president for the investigations.
