Last year, some of their texts provided even more ammo to the FBI, Justice Department, and Mueller's critics.
The messages between FBI lawyer Lisa Page and her lover and bureau colleague Peter Strzok by the Senate Homeland Security Committee, which provides oversight of the bureau. He also wanted Clinton to defeat Trump in the election - in another message, he wrote: "God Hillary should win 100,000,000 - 0".
He added that Strzok and Page also resented Trump's supporters and the "ignorant hillbillys [sic]" who voted against then-FBI Deputy Director Andrew McCabe's wife for a state Senate seat.
It's worth noting that the text exchange reveals that those emails were found on September 28, 2016, a month before Comey publicly informed Congress about reopening the probe.
It was on October 28, 2016 that Comey informed Congress that, "Due to recent developments", the FBI was re-opening its investigation into Clinton's use of a private email server to conduct government business.More news: US warns countries against aiding terrorists eyeing nuclear weapons
"This man cannot be president", Page wrote in March 2016. "Figure I need to brush up on Watergate".
On May 19, 2017, two days after Mueller's appointment, Strzok gleefully talked with Page of being involved in "A case which will be in the history books" and "An investigation leading to impeachment?"
"Potus wants to know everything we're doing", Page wrote to Strzok according to Fox News.
On Nov. 13, 2016, Page told Strzok: "I bought all the president's men". Mr. Strzok was the lead investigator on the Clinton email probe.
"No one noticed. And while minor, it cuts against, 'I never send or received anything marked classified", he wrote.
On November 14, Page references a meeting that makes her angry, because there is "lots of high fallutin' [sic] national security talk".
They frequently texted each other news stories about Russian election meddling, denigrated Trump associate Roger Stone and, in one profanity-laced message, Strzok cursed out the "cheating [expletive] Russians". "Meanwhile, we have OUR task ahead of us".
The Justice Department watchdog briefed a bipartisan group of lawmakers Tuesday on its investigation into the FBI's actions during the 2016 election, including its probe into Hillary Clinton's emails.
