Donald Trump said Thursday he may pull acting Attorney General Todd Blanche’s nomination for the full-time post to avoid conceding to Senate Republicans’ demands over a sweeping tax audit immunity deal benefiting the president and members of his family.

After failed negotiations forced the delay of a committee vote to advance Blanche’s nomination, Trump suggested he was holding firm against pressure from Republican Sens. John Cornyn and Thom Tillis. They have expressed concerns about the controversial settlement of Trump’s lawsuit against the Internal Revenue Service, which a judge denounced as an exercise in self-dealing.

The senators said the Justice Department seemed interested in reaching an agreement with them, but the White House wouldn’t budge to aid the confirmation of Trump’s loyal former personal attorney, who has aggressively pursued the administration’s priorities as acting attorney general. Instead, Trump said in a social media post that he might pull Blanche’s nomination and resubmit it after Cornyn and Tillis leave office next year.
