— -- President Trump sparked a firestorm this morning when he suggested that his predecessor, Barack Obama, had ordered wiretaps on Trump Tower prior to the November 2016 election.

An Obama spokesperson vehemently denied the former president's involvement, saying: "A cardinal rule of the Obama administration was that no White House official ever interfered with any independent investigation led by the Department of Justice. As part of that practice, neither President Obama nor any White House official ever ordered surveillance on any U.S. citizen. Any suggestion otherwise is simply false."

The president has already faced massive scrutiny over his campaign's alleged contacts with Russian officials -- an assertion Trump has repeatedly denied as "fake news." It has been widely reported that Attorney General Jeff Sessions, a Trump campaign surrogate, and Trump's son-in-law and senior adviser, Jared Kushner, met with the Russian ambassador before the inauguration.

Trump's remarks raise questions about whether a wiretap on Trump Tower could have been legally approved, possibly through a FISA court. Here's what you need to know.
