WASHINGTON (Reuters) - President Donald Trump has authorized the FBI to expand its investigation into sexual misconduct allegations facing Supreme Court nominee Brett Kavanaugh, the New York Times reported on Monday, citing two people briefed on the matter.

The Times also reported that the FBI has already concluded interviews with the four witnesses its agents were originally asked to talk to, according to the two people. Reuters could not immediately verify the report.
