Hours after he took the oath of office on Friday, President Donald Trump began turning his campaign promises into reality when he signed an executive order to start undoing the Affordable Care Act. Here's a look at some of the other changes, big and small, that the new president has said are coming soon.

100-day agenda Before the election, Trump released an outline of actions he would take in his first 100 days, including:

• Propose a constitutional amendment to impose term limits on all members of Congress.

• A hiring freeze on all federal employees to reduce the federal workforce through attrition, exempting military, public safety and public health.

• A requirement that for every new federal regulation, two existing regulations must be eliminated.

• A five-year ban on White House and congressional officials becoming lobbyists after they leave government service.

• A lifetime ban on White House officials lobbying on behalf of a foreign government.

• Lift restrictions on the production of $50 trillion dollars' worth of U.S. energy reserves, including shale, oil, natural gas and clean coal.

• Allow energy infrastructure projects, like the Keystone XL pipeline, to move forward.

• Cancel billions in payments to U.N. climate change programs and use the money for U.S. infrastructure.
