Donald Trump and 2020 democratic candidate Michael Bloomberg got in a war of words Tuesday afternoon with the commander-in-chief claiming he would love to run against the former New York City major over Senator Bernie Sanders.

Trump, billing Bloomberg as “Mini Mike,” wrote that the former mayor’s campaign is no more than that of “a large scale illegal campaign contribution,” adding that he is “illegally buying the Democrat Nomination.”

A reminder that Trump is 73 and Bloomberg is 77.

What Mini Mike is doing is nothing less than a large scale illegal campaign contribution. He is “spreading” money all over the place, only to have recipients of his cash payments, many former opponents, happily joining or supporting his campaign. Isn’t that called a payoff? …..

…..Mini is illegally buying the Democrat Nomination. They are taking it away from Bernie again. Mini Mike, Major Party Nominations are not for sale! Good luck in the debate tomorrow night and remember, no standing on boxes!

Bloomberg responded asking why Trump wants to run against Sanders “so badly.”

Trump shot back that that come November 2020 he would like to face Bloomberg as a Democratic rival:

Mini Mike. No, I would rather run against you!

Bloomberg tweeted back, “See you in November.”

Can't trust a word you say – and now you want us to believe you?

See you in November. https://t.co/GkKkoXNY6T

And then Trump, being Trump, took the low road and retweeted a video that makes Bloomberg look like he’s about 4 feet tall:
