U.S. Sen. Joni Ernst's vote for President Donald Trump's "big, beautiful bill" could be a defining issue in her reelection race.

The bill continues tax cuts from President Trump's first stint in the White House, funds his border wall plan, and increases defense spending. The associated fiscal impact of this is offset by reducing federal support for key components of the social safety net, including food assistance and health coverage programs.

The House voted overnight Thursday, after hours of delay, to advance President Trump's "big, beautiful bill" before a final vote, which is expected soon.
