President Trump's legal team plans to file its complaint against former FBI Director James Comey with the Justice Department inspector general and the Senate Judiciary Committee as early as next week.

A source close to Trump outside counsel Marc Kasowitz's team said they are "looking toward next week" to file the complaint. Lawyers are working to make sure the submissions are "thorough and complete," the source told the Washington Examiner on Friday.

Trump's legal team began planning to file a complaint against Comey after his testimony before the Senate Intelligence Committee earlier this month.

In his testimony, Comey said the White House defamed him and expressed concern that Trump "might lie" about the nature of one of their meetings. The fired FBI director also admitted to sharing memos he had written detailing his conversations with Trump with a friend so that he would release them to the press.

Following the testimony, Trump accused Comey of lying and leaking information.

"Despite so many false statements and lies, total and complete vindication...and WOW, Comey is a leaker!" Trump tweeted.

Kasowitz has represented Trump in numerous prior cases, and he was hired by the president in late May to help him with the ongoing federal investigation into Russian meddling in the 2016 presidential election.
