Former Trump aide Kash Patel testifies before grand jury in Mar-a-Lago documents investigation

An aide to former President Donald Trump acknowledged Friday that he appeared before a grand jury investigating White House documents recovered from Trump's Mar-a-Lago home in Palm Beach, Fla.

A spokesperson for Kash Patel, who served in the Trump White House in intelligence and defense roles and was designated by Trump to be a representative to the National Archives and Records Administration, said in a statement to CBS News that Patel testified to the Washington, D.C. grand jury Thursday. 

The spokesperson, Erica Knight, did not describe Patel's testimony, but said "his testimony was compelled over his objection through the only legal means available to the government — a grant of limited immunity."
