President Donald Trump said he may withdraw Todd Blanche’s nomination for attorney general until two Republican Senate holdouts leave office, escalating a dispute within his own party. The move matters because the Senate Judiciary Committee has delayed a vote on Blanche, leaving Trump’s preferred Justice Department leader in an acting role and exposing limits on party unity.

Republican Senators John Cornyn of Texas and Thom Tillis of North Carolina have sought written assurances over a proposed “Anti-Weaponization Fund” and the terms of Trump’s tax-immunity settlement with the Internal Revenue Service. Cornyn wants the tax arrangement limited to existing audits rather than future tax returns, while Trump has praised Blanche as a “star” and said he would keep him as acting attorney general.
