WaPo:

Former President Donald Trump is considering sending a letter to Stephen K. Bannon saying that he is waiving his claim of executive privilege, potentially clearing the way for his former chief strategist to testify before the House select committee investigating the pro-Trump riot at the Capitol.

The letter would reiterate that Trump invoked executive privilege in September 2021, when Bannon was first subpoenaed by the House committee. But it would say that the former president is now willing to give up that claim — the validity of which has been disputed — if Bannon can reach an agreement on the terms of an appearance before the panel. The letter was described by three people familiar with it, who spoke on the condition of anonymity because of the matter’s sensitivity.

Some advisers were seeking to talk Trump out of signing the letter.
