(CNN) Senate Intelligence Chairman Richard Burr said Tuesday he did not inform the White House about details of the FBI counterintelligence investigation into members of Trump's team following a March 2017 briefing on the investigation from then-FBI Director James Comey.

Burr, the North Carolina Republican who leads the Senate's ongoing investigation into Russian election meddling , has faced questions about what he told the White House counsel's office after he was referenced in special counsel Robert Mueller's report on obstruction of justice. Mueller wrote that the White House counsel's office was in touch with Burr in March 2017 "about the Russia investigations and appears to have received information about the status of the FBI investigation."

Asked if he took information he learned from Comey proactively to the White House, Burr said: "No."

The report says Burr was referenced in notes from Annie Donaldson, deputy counsel to former White House counsel Don McGahn. Donaldson wrote Burr briefed the counsel's office on the "existence of 4-5 targets" following a briefing that Comey gave to the Gang of Eight, the group of intelligence and congressional leaders from both parties who receive sensitive information from the executive branch.

"The notes on their face reference the FBI, the Department of Justice and Comey; and the notes track the background materials prepared by the FBI for Comey's briefing to the Gang of 8 on March 9," the report says, listing the targets referenced as former national security adviser Michael Flynn , former Trump campaign chairman Paul Manafort , former Trump campaign adviser George Papadopoulos and one name that's redacted due to an ongoing investigation.
