Donald Trump Victory Leaves Obama Legacy Hanging in the Balance

The president-elect has promised to undo many of Obama's signature initiatives

Trump's victory appears to be a huge blow to the nation's first black president, who is among one of the most popular outgoing presidents in recent history. A recent Gallup tracking poll found President Obama enjoying a 56 percent approval rating.

With Trump in the White House and Republicans controlling both chambers of Congress, many of the president's legislative accomplishments and executive actions could unravel. Here's a look at a few areas that Trump may try to chip away.

Throughout his campaign, Trump has vowed to work to repeal and replace the president's signature healthcare plan, saying it's an item he will tackle on "day one" in the White House. In the final week of the campaign, Trump suggested he could convene a special session of Congress to repeal the Affordable Care Act, which has been the target of Republican ire for the past six years.

Trump says he would cancel the Paris Climate Agreement, which went into effect last week and aims to limit the rise of world temperatures to "well below" two degrees Celsius. He would also eliminate the Clean Power Plan, which aims to curb greenhouse gas emissions from power plants.
