To the surprise of absolutely no one, Sen. Martha McSally has “heard enough.”

She doesn’t need to hear from any witnesses in President Donald Trump’s impeachment trial.

Certainly not from former National Security Adviser John Bolton, who claims to have direct knowledge about Trump’s involvement in and motives for freezing military aide to Ukraine.

No need to hear from or cross examine the man who not even two years ago earned her praise for being "exceptionally qualified," not to mention “frank and direct.”

That, however, was then, when Bolton was on Team Trump.

This is now, when he’s ... not.

McSally doesn't want to hear from Bolton

And so comes McSally’s Wednesday evening announcement – tweeted just four hours after Trump tweeted “GAME OVER”, along with an August video of a Bolton interview with Radio Free Europe.

In the video clip, Bolton expresses no concern about Trump’s July 25 phone call with Ukraine President Volodymyr Zelensky, which he described as “warm and cordial.”

That, apparently, is enough for Martha McSally. Never mind that Bolton is now claiming, in the manuscript of his soon-to-be published book, that Trump told him he wanted to tie military aid to Ukraine to an investigation into Joe Biden and his son Hunter.

McSally doesn’t need – or want – to hear it.

“I have heard enough,” she tweeted on Wednesday evening. “It is time to vote.

“The House Democrats have repeatedly claimed their case has overwhelming evidence — the same House Democrats who could have handled this matter through a bipartisan oversight process.

“A dangerous precedent will be set if we condone a rushed, partisan House impeachment with no due process that shuts down the Senate for weeks or months to do the House's work.”

Better, apparently, to have a rushed "trial" with not a single witness called to testify.

Not. One.

A juror listens to witnesses, senator

I can’t imagine that anybody really believes that McSally sat even for a second as a juror.

But then, McSally faces a tough election this year and must be terrified at the prospect of crossing Trump.

Even before the rough transcript of Trump’s July phone call with Zelensky was released, she was rushing to Trump’s defense, excoriating Democrats for launching an impeachment inquiry.

Just 13 days ago, McSally raised her right hand and took an oath to uphold “impartial justice.” Apparently, while we were looking at her right hand, the fingers on her left hand were crossed.

The role of a juror is to hear from witnesses, to determine what is true and what is not.

McSally, however, doesn’t need to hear from anyone.

Not even from Bolton, a conservative Republican and career diplomat who has served every Republican administration since Ronald Reagan – a guy often praised as a straight talking foreign policy hawk.

That’s hawk, Sen. McSally – not hack.
