A commercial produced by a billionaire from California calling for President Trump’s impeachment began running on Fox News last week. Since then, hedge fund guru Tom Steyer’s website, “Needtoimpeach.com,” has been very busy.

Steyer, who was a huge donor to both Barack Obama and Hillary Clinton, launched a TV commercial as part of his vow to spend $10M to get the message out that Trump is mentally incompetent and a clear and present danger to the United States.

A petition launched by Steyer to impeach the president has reportedly gathered a staggering number of signatures in just ten days.  The petition has been signed nearly 1.2 times, according to the liberal-leaning news blog, Axios.

Trump responded to Steyer’s calls for impeachment on Twitter, calling him “wacky” and “unhinged.”
