Lawyers for the official have voiced concern about the person's safety and that testifying in person to congressional aides could expose the person's identity. They have attributed some of that concern to statements by Trump, who calls the inquiry a sham and has suggested the whistleblower committed treason. US officials told Reuters last week that the government was providing security for the whistleblower. A proposal was made for the whistleblower to answer questions in writing, the two sources said, and House aides accepted it in principle. In the complaint since made public, the whistleblower said the information about the call came from White House officials.
