(CNN) Acting Director of National Intelligence Richard Grenell sent a letter to Democratic Rep. Adam Schiff on Monday flouting the House Intelligence Committee chairman's demand for information about the actions Grenell has taken since becoming the top US intelligence official last month.

Grenell's letter instead included a litany of charges against Schiff, accusing him of trying change his committee's mandate to be in charge of intelligence community "administration," of attacking career intelligence officials and of not supporting the women now leading the National Counterterrorism Center after a longtime career official was fired.

"Going forward, I encourage you to think of the relationship between your committee and the IC as that between the legislative and executive branches of government, rather than that between a hedge fund and a distressed asset, as your letter suggests," Grenell wrote, according to a copy obtained by CNN.

The letter comes after Schiff wrote to Grenell earlier this month expressing concerns over recent personnel changes at the agency that have been carried out amid the coronavirus outbreak, including the firing of the Intelligence Community Inspector General who informed Congress about the whistleblower complaint that led to President Donald Trump's impeachment.

Specifically, Schiff questioned whether the moves were "inappropriately influenced by political considerations."
