President Donald Trump kicked off his Friday by attacking the U.S. intelligence community once again. He lashed out at the FBI, tweeting that the agency is “totally unable to stop national security ‘leakers.’”

The FBI is totally unable to stop the national security "leakers" that have permeated our government for a long time. They can't even......

Trump’s outburst comes hours after CNN and The Associated Press reported that White House chief of staff Reince Priebus had asked the FBI to publicly dispute reports that the president’s team had communicated with Russian officials throughout the 2016 presidential campaign.

FBI director James Comey reportedly refused to comply with the request because of the agency’s ongoing investigation into Trump’s associates and their potentially illegal links to the Kremlin.

Comey was criticized after he decided just days before the 2016 election to reinvestigate the emails of Democratic presidential candidate Hillary Clinton. Though the investigation didn’t turn up any damning new information, Democrats have said that it damaged Clinton’s election chances.

The White House has repeatedly denied allegations that Trump associates kept “constant communication” with Russian officials during the campaign, as first reported by The New York Times and CNN this month.

Trump’s Friday tweet didn’t deny accusations that the White House attempted to meddle in the FBI’s investigation, but instead took aim at FBI “leakers” who could have a “devastating effect” on the U.S.
