Over the weekend, President Trump made the bold and still unsubstantiated claim that President Barack Obama wiretapped Trump Tower before the election. Without any proof to back this up – outside of some early morning tweets, many called Trump out for unnecessarily stirring the pot and were noticeably bothered.

According to those close to him, Obama is just as bothered by Trump’s claims as anyone else, if not more. CNN even used the word “furious” when former aides spoke on how Obama was feeling.

“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,” said Kevin Lewis, Obama’s spokesman. “As part of that practice, neither President Obama nor any White House official ever ordered surveillance on any US citizen. Any suggestion otherwise is simply false.”

Trump went on to call Obama a “bad or sick guy” for allegedly using his power as president to spy on him.

To make matters worse, CNN reports that Sen. Lindsey Graham is preparing to subpeona the FBI to find out once and for all if the Obama administration did what Trump claims.

“All I can say is that the country needs an answer to this. The current President has accused the former President of basically wiretapping his campaign,” Graham said.

This is the kind of chaos that can be started when the president chooses to vent his frustrations in public and forces the government to respond in a similar public manner.
