Poll: 82 percent think Trump should testify under oath to Mueller
A vast majority of Americans say President Trump should be interviewed under oath by special counsel Robert Mueller.
More than 70 percent say Trump should agree to an interview, and if he does, 82 percent say it should be under oath, according to a new Monmouth University poll.
Multiple reports over the past several weeks have indicated that it's likely Mueller will interview Trump as part of the probe into Russian election meddling and possible collusion between the Trump campaign and Russia. As it's a crime to lie to the FBI regardless of whether an oath was administered, Trump would not be expected to take an oath if he agrees to an interview with Mueller.
However, if he were to refuse the interview, the special counsel could potentially issue a subpoena for Trump to testify before a grand jury, in which case the president would be required to take an oath.
