Washington (CNN) Former acting Director of National Intelligence Joseph Maguire has formally resigned from US government service after President Donald Trump made it clear he would not be nominated for the full time intelligence chief job, a source familiar with the matter tells CNN.

The office of DNI also officially announced the second-ranking official there, Andrew Hallman, stepped down Friday afternoon. Despite leaving ODNI, Hallman could take another role in the intelligence community.

President Donald Trump became irate in a meeting with Maguire last week for allowing lawmakers to be briefed about the intelligence community's belief that Russia is already taking steps to interfere in the 2020 election with the goal of helping Trump win, a White House official has told CNN.

Former acting Director of National Intelligence Joseph Maguire testifies before a House Select Committee in 2019 regarding the whistleblower complaint.

On Wednesday, Trump announced he was naming Richard Grenell , a staunch loyalist and current US ambassador to Germany, as acting DNI despite him not having experience in intelligence.

Democrats are raising fresh concerns about the appointment of Grenell, who does not have intelligence experience, and whether he was moved into the role in reaction to Trump's anger toward Maguire over the briefing.
