Mike Pence testifies in criminal probe of Trump and Capitol riot
Former US Vice-President Mike Pence has testified as part of a criminal investigation into alleged efforts by Donald Trump to overturn his defeat in the 2020 election.
Mr Pence, 63, sat for more than seven hours before a federal grand jury in Washington DC, sources told the BBC's US partner CBS News.
He was issued with a subpoena to testify under oath earlier this year.
The questioning by prosecutors took place behind closed doors.
His appearance on Thursday came just hours after an appeals court rejected a last-ditch bid by Mr Trump's legal team to stop Mr Pence from testifying.
Mr Pence's lawyers had also sought unsuccessfully to challenge the subpoena, arguing that his role as president of the Senate during his time in office meant he had congressional immunity.
