US President Donald Trump signed his first executive order on Friday to "ease the burden of Obamacare", the signature healthcare law introduced by Barack Obama which Trump had pledged to repeal.
Trump's chief of staff, Reince Preibus directed an immediate regulatory freeze for all government agencies, White House spokesman Sean Spicer said.
Spicer said the order was aimed "to ease the burden of Obamacare as we transition from repeal and replace."
He did not give any further details.
During the presidential campaign, Trump had vowed to scrap the Affordable Care Act or Obamacare, but Republicans have yet to find a replacement for the healthcare programme which provided health insurance to more than 20 million people.
Trump also confirmed the appointments of his Defence secretary James Mattis and Homeland Security secretary John Kelly.
The Senate voted 98-1 confirming Mattis and 88-11 in favour of Kelly.
Vice President Mike Pence swore Mattis and Kelly in a separate ceremony.
Trump also told reporters, "It was busy, but good. It was a beautiful day."
