Rowan Scarborough writes in the Washington Times about ongoing efforts to undermine the Trump administration.

From the moment Donald Trump secured the Republican nomination and then the presidency, national security officials under President Obama have shown themselves to be intense adversaries in public and behind the scenes.

In the latest development, special counsel Robert Mueller’s top-gun prosecutor, Andrew Weissmann, praised acting Attorney General Sally Yates, a Trump nemesis, for refusing a White House order to defend the president’s travel ban on Muslim-majority countries, according to internal emails.

Mr. Weissmann made it clear whose side he was on.

“I am so proud,” Mr. Weissmann wrote to Ms. Yates when he was the head of the Obama Justice Department’s criminal fraud division. “And in awe. Thank you so much. All my deepest respect.”

The U.S. Supreme Court this week approved Mr. Trump’s travel ban of targeted nations in a 7-2 ruling.

Mr. Weissmann, who as a private lawyer donated to Mr. Obama and to New York Gov. Andrew Cuomo, another Democrat, now is Mr. Mueller’s right-hand man. He oversaw the investigation of former Trump campaign manager Paul Manafort, including a pre-dawn FBI raid on his condo and an in-bed frisking of his wife.

The Weissmann emails and others from Obama political appointees praising Ms. Yates were unearthed in a Freedom of Information Act request by the conservative government watchdog Judicial Watch.

Mr. Trump fired Ms. Yates as she became a hero to Mr. Weissmann and other liberals.

The anti-Trump moves by Obama aides began in July 2016 during his campaign for the presidency.
