A top prosecutor working with special counsel Robert Mueller praised former Acting Attorney General Sally Yates at a moment in late January when she was at loggerheads with newly minted president Donald Trump.

Andrew Weissman emailed Yates ten days into the Trump administration after she refused to enforce or defend an executive order banning incoming travelers to the U.S. from seven terror-prone majority Muslim countries.

'I am so proud. And in awe. Thank you so much. All my deepest respects,' Weissman wrote to her.

Andrew Weissmann, a top prosecutor working with special counsel Robert Mueller, let his partisanship show in a glowing January email to then-Acting Attorney General sally Yates

Yates, a holdover from the Obama administration, had just announced her refusal to enforce President Donald Trump's seven-nation travel ban

'I am so proud. And in awe. Thank you so much,' Weissman wrote January 30; Trump fired Yates that night

The message, sent January 30 to Yates' government email account, was one of hundreds of pages of documents newly obtained by Judicial Watch, a right-leaning advocacy group.

Trump fired Yates later that same day. As she packed up her things, she forwarded some emails to her personal account, including Weissman's.

News of Weissman's partisanship comes after another top Mueller aide, Peter Strzok, was demoted and reassigned following the revelation that he was sending anti-Trump text messages to his lover – another Justice Department lawyer.

'This is an astonishing and disturbing find,' Judicial Watch president Tom Fitton said Tuesday in a statement.

Peter Strzok, involved in both Trump and Clinton-focused Justice Department probes, texted his lover anti-Trump messages

'Andrew Weisman, a key prosecutor on Robert Mueller’s team, praised Obama DOJ holdover Sally Yates after she lawlessly thwarted President Trump. How much more evidence do we need that the Mueller operation has been irredeemably compromised by anti-Trump partisans? Shut it down.'

Weissman was the driving force behind obtaining indictments against former Trump campaign manager Paul Manafort.

The New York Times in late Obtober described him as 'a top lieutenant' to Mueller 'on the special counsel investigation into Russian interference in the 2016 election and possible links to the Trump campaign.'

Strzok, the more overtly partisan prosecutor, changed language in a controversial statement by then-FBI director James Comey that declared Hillary Clinton 'extremely careless' with her private email server.

Comey's original remarks had said Clinton was 'grossly negligent,' a phrase that mirrored language in the federal criminal code about handling classified documents.

Strzok also had a direct hand in interviewing former National Security Advisor Michael Flynn, who pleaded guilty last week to a charge of lying to the FBI.

And he oversaw FBI interviews with Clinton aides Cheryl Mills and Huma Abedin, both of whom shaded the truth about their knowledge of the server but were spared legal trouble.
