The showdown between House and Senate Republicans is escalating as the two groups barrel ahead with their contrasting strategies to pass President Trump’s legislative agenda — with the upper chamber expected to move this week.

Senate Republicans took a major step to advance President Donald Trump’s sweeping agenda early Friday morning, voting to adopt a budget blueprint that sets up a clash with House Republicans, who have put forward a competing plan.

The Senate, working into the morning hours Friday, passed the first of two budget bills, focusing on border security, immigration and tax breaks.
