The day Donald Trump stops taking to twitter and making claims that aren’t backed by factual evidence will be the day hell freezes over. One of Trump’s most recent claims accuses former president Barack Obama of wire-tapping Trump Tower during the 45th president’s campaign, according to Quartz writer Ephrat Livni.

Livni added that from these accusations, Obama had grounds to sue Trump for libel over his “defamatory words.”

Libel is defined as a published, written statement that inflicts damage upon the reputation of another. Accusing Obama of illegal wire-tapping, a federal offense, means Trump could be sued for threatening the former president’s reputation.

While Trump has been vocal about his distaste for the media and “fake news,” he should be more cautious to make sure he is not aiding and abetting the spread of this “fake news.”

Sooner or later, Trump might land himself in hot water with the law over his words. According to Joel Rose’s NPR article, Trump already faces over 50 lawsuits after just two weeks in office. What’s one more added to that impressive collection?

And remember, Mr. President, once it’s on the internet, it’s there forever.
