The judge in the fraud trial of former Trump campaign chairman Paul Manafort says he has received threats.
He will also not release the names of jurors at the trial's conclusion because he fears for their safety.
Judge TS Ellis III said he is under the protection of US Marshals and is concerned for the "peace and safety of the jurors" during a hearing on Friday.
He said he personally received threats but declined to delve into specifics, adding that he was taken aback by the level of interest in the trial.
Jury deliberations began on Thursday in the tax and bank fraud trial of President Donald Trump's former campaign chairman Paul Manafort.
Prosecutors say he hid tens of millions of dollars in foreign income from the IRS – money he made advising politicians in Ukraine.
Defence lawyers say the government failed to prove its case.
Mr Trump called Manafort a "very good person" as the jury began its second day of deliberations on Friday.
He said at the White House that it was "a very sad day for our country" and that Manafort had "worked for me for a very short period of time".
