Pres. Donald Trump uses first act in oval office to sign executive order on Obamacare

Donald Trump vowed to repeal Obamacare if he was elected as President of the United States. And sure enough, shortly after his inauguration has ended, he made the Affordable Care Act the subject of his first executive order signed in the Oval Office.

Trump directed agencies to ease the regulatory burdens associated with Obamacare as the US Congress determines how to repeal and replace the health care law.

Trump also signed the commissions for his Defense Secretary James Mattis and his Homeland Security Secretary John Kelly, who were confirmed by the Senate on Friday.

White House spokesman Sean Spicer also told reporters that Trump's Chief of Staff Reince Preibus is sending a memo to agencies directing an immediate regulatory freeze.
