Washington CNN  — 

In his final hours as the top US intelligence official, Richard Grenell took one last swipe at congressional Democrats and declassified more documents tied to the origins of the Russia investigation. His actions were emblematic of a short but consequential and controversial tenure as the acting director of national intelligence.

Grenell attacked the top Democrat on the Senate Intelligence Committee in a letter on Monday, accusing Virginia Sen. Mark Warner of “cherry picking certain documents for release” for political reasons. He also declassified additional documents related to the Russia investigation before walking out the door, according to Fox News, documents that his now-former boss, President Donald Trump, has seized on.

The pair of actions were the final notes of Grenell’s combative record since being appointed acting DNI in February. Grenell, the US Ambassador to Germany, was criticized by Democrats and career intelligence officials as the least-experienced and most overtly political official to serve as the DNI, and they say that their worst fears have been realized: that the fierce political loyalist weaponized the US intelligence apparatus to boost Trump’s reelection bid.
