All four White House officials who are scheduled to give depositions on Monday during the House’s impeachment inquiry won’t show up, as a source with knowledge of the situation tells CNN that National Security Council lawyers John Eisenberg and Michael Ellis will not testify.

The two officials will join Robert Blair, assistant to the President and senior adviser to the acting White House chief of staff Mick Mulvaney, and Brian McCormack, associate director for natural resources, energy & science at the Office of Management and Budget, in not testifying on Monday, CNN reported earlier. Energy Secretary Rick Perry, who was scheduled to appear Wednesday, will not participate in a closed door deposition, an Energy Department spokesperson said Friday.

An administration official says Eisenberg isn’t showing up due to executive privilege while Blair, Ellis and McCormack aren’t going to appear because they won’t be able to have an administration lawyer present.
