WASHINGTON (AP) — President Donald Trump says he may withdraw and delay Todd Blanche’s nomination as attorney general until Republican senators who are seeking concessions from the top prosecutor leave office.

Trump doubled down Thursday on choosing his former personal lawyer as the nation’s top lawman, calling him “a STAR” and said he will keep in the role as acting attorney general until Republican Sens. John Cornyn of Texas and Thom Tillis of North Carolina leave office.

“I have no objection to temporarily withdrawing Todd’s name,” Trump posted Thursday on his social media site. “If they do not do the right thing, and putting him back after Cornyn and Tillis are out of office.”

Cornyn and Tillis both leave office next year. They have sought additional assurances in writing spelling a final end to that an “Anti-Weaponization Fund” as part of Trump’s lawsuit against the Internal Revenue Service.
