President Donald Trump's speech at the Iowa State Fairgrounds marks the kickoff of the yearlong celebration of America's 250th birthday.

Trump took the stage in the Hawkeye State and championed the GOP-led "big, beautiful bill" while attacking Democrats who opposed it.

DES MOINES, Iowa (AP) — President Donald Trump campaigned on a promise to deliver a “spectacular” yearlong birthday party to mark 250 years of American independence. On Thursday, he will be in the U.S. heartland to kick off the patriotic festivities — and to celebrate the final passage of his sweeping tax cuts and spending package.
