With full faith, honor, and integrity.

The FBI warned a supervisory agent who investigated Hunter Biden that he was expected to “decline to respond” to House Oversight Committee questions about the “ongoing” case involving the first son, a bombshell letter obtained by The Post shows.

FBI general counsel Jason Jones sent the letter Sunday afternoon, just hours before the agent was set to testify — even though a source tells The Post that the FBI knew of a scheduled Monday deposition for several days.

“[T]he Department expects that you will decline to respond to questions seeking non-public information likely covered by one or more components of executive privilege or other significant confidentiality interests, in particular information about deliberations or ongoing investigative activity in law enforcement matters,” Jones wrote.

“You should instead refer such questions to the FBI’s Office of Congressional Affairs,” the FBI lawyer went on.

Which will of course refuse to answer those questions. I do like how executive privilege covers the president’s son. The same administration that claims executive privilege doesn’t cover Jared Kushner has apparently quietly decided to invoke it on behalf of Hunter Biden. Or the FBI has decided to treat it as potentially invokable.

Again this dismantles the defense that Hunter Biden’s scandals have nothing to do with his father.

Thus far we’ve seen the FBI tip off the Biden transition team that a raid was imminent. Now executive privilege is in play. Can the White House invoke executive privilege if this didn’t affect Joe Biden? Safe bet that it does.
