Washington — The House convened Wednesday to take up President Trump's Senate-passed massive domestic policy bill, to approve changes to the legislation ahead of a July 4 deadline to get the bill to the president's desk for his signature.

Now, the legislation goes back to the lower chamber, where House Speaker Mike Johnson (R-LA) and other GOP leaders are corralling votes. The House narrowly passed the bill last month in a 215-214 vote, and now that several modifications have been made to the text, more than two dozen House members are currently holdouts.

With a July 4 deadline looming, here are the basics of President Donald Trump's Big Beautiful Bill and how the Senate and House versions differ.
