Question

can the president refuse to sign a bill​

Answer 1

Answer:

The power of the President to refuse to approve a bill or joint resolution and thus prevent its enactment into law is the veto. The president has ten days (excluding Sundays) to sign a bill passed by Congress. ... This veto can be overridden only by a two-thirds vote in both the Senate and the House.

Answer 2

Answer:

Yes.

The president can either give his assent to the bill, reject the bill or send it back with recommendations. If the bill is passed second time, he has to give his assent.
