Indiana becomes the second GOP-led state in recent weeks to resist Trump’s push for new maps designed to strengthen GOP prospects.

The filibuster, a long-standing Senate rule, allows a single senator to block most legislation unless 60 senators vote to cut off debate. Democrats have used the filibuster to block Republicans’ government funding bill for more than a month despite Republicans’ 53-seat Senate majority.

The senators’ comments came after House Speaker Mike Johnson said he would hold a vote on the House floor to repeal the provision inserted by his Senate counterparts.

President Donald Trump has urged Senate Republicans to redirect funds from "money sucking" insurance companies linked to Obamacare back to Americans.
