which republican senators do not support nuking the filibuster for the save act despite trump's demand

Republican senators who have not backed nuking the filibuster for the SAVE Act include John Thune and Thom Tillis ; Mike Lee and Rick Scott have been more open to rule changes, while John Cornyn later said he supported whatever Senate-rule changes were needed.

What the reporting shows

• John Thune said changing filibuster rules for the SAVE Act was not realistic.

• Thom Tillis called ending the filibuster a “foolish and lazy idea” and said he would not vote for it.

• Lisa Murkowski was also described as opposed to the proposal, though she is a GOP senator from Alaska rather than part of the Trump-aligned push.

Why this is the answer

The reporting says the Republican conference does not have the votes for a filibuster change, and Thune has publicly acknowledged that reality. So the clearest Republicans on the “no” side are Thune and Tillis, with Murkowski also opposed.
