President Trump said Sunday that he would consider not signing an upcoming coronavirus relief package if it doesn’t include a payroll tax cut.

“I’ll have to see, but yeah, I would consider not signing it if we don’t have a payroll tax cut,” Trump told Fox News’s Chris Wallace in an interview that aired Sunday.

The president insisted that “a lot of Republicans” are in favor of a payroll tax holiday, though some Republicans have been cool to the proposal since Trump floated it earlier this year. Democrats have opposed the idea of a payroll tax cut.

Trump has previously said he wants to see a payroll tax cut in the next coronavirus relief bill, and the White House suggested last week that the measure was non-negotiable.
