Senators John Cornyn of Texas and Thom Tillis of North Carolina had said they would not confirm Blanche unless he narrowed the scope of the I.R.S. immunity order.
After he did so, while still shielding the president, his sons and their company, the senators said they would support’s Blanche’s confirmation.
The initial wording of Mr. Blanche’s May 19 order also seemed to extend the protection not only to Mr. Trump, but to his entire family “without limitation” and any companies they were connected to. That raised the possibility of a huge pool of people and companies claiming immunity under the deal.
