The House took a critical step toward approving their mammoth tax and spending package early Thursday morning by adopting a rule for the measure after tamping down a revolt.

House Republican leaders are scrambling to shore up support for President Trump's massive domestic policy bill amid pushback to the Senate's changes, as the GOP seeks to approve the final version of the legislation ahead of a July 4 deadline to get the bill to the president's desk.

The bill would add $3.4 trillion to the nation’s $36.2 trillion debt. President Donald Trump’s tax-cut package cleared its final hurdle in the U.S. Congress on Thursday, as the Republican-controlled House of Representatives narrowly approved the massive bill and sent it to him to sign into law.
