President Trump did not wait long after former Starbuck’s CEO Howard Schultz announced he was considering a 2020 presidential run to launch an attack.

According to Fox News:

President Trump on Monday fired back at Howard Schultz, saying the former Starbucks CEO doesn’t have the “guts” to run for president after he announced he was mulling a2020 White House bid as an independent — and took a few shots at Trump himself.

“Howard Schultz doesn’t have the ‘guts’ to run for President! Watched him on @60Minutes last night and I agree with him that he is not the ‘smartest person.’ Besides, America already has that! I only hope that Starbucks is still paying me their rent in Trump Tower!” Trump tweeted Monday morning.

The president’s tweet comes after Schultz’s interview on CBS News’ “60 Minutes,” where he revealed he was “seriously thinking” about running for president in 2020 as a “centrist independent,” and challenged Trump’s fitness for office.

“We’re living at a most fragile time, not only the fact that this president is not qualified to be the president, but the fact that both parties are consistently not doing what’s necessary on behalf of the American people,” Schultz said, specifically citing the national debt as “a reckless example, not only of Republicans but of Democrats, as well, as a reckless failure of their constitutional responsibility.”

Some Democrats are even calling for a boycott of Starbucks because as an Independent candidate they view Schultz as a threat to steal votes from a Dem challenger to Trump.
