Donald Trump welcomes former vice president Joe Biden to the 2020 presidential race:  “You will be dealing with some sick and demented people.”

Trump tweeted:  “Welcome to the race Sleepy Joe. I only hope you have the intelligence, long in doubt, to wage a successful primary campaign. It will be nasty – you will be dealing with people who truly have some very sick & demented ideas. But if you make it, I will see you at the Starting Gate!”

Biden ripped Trump in his announcement, saying he will change the face of this country in ugly ways if he wins reelection.

“I believe history will look back on four years of this president and all he embraces as an aberrant moment in time, but if we give Donald Trump eight years in the White House, he will forever and fundamentally alter the character of this nation, who we are, and I can not stand by and watch that happen.”
