Obviously there is a war going on between Donald Trump and Mitt Romney and Trump is doing what he does best: complaining on Twitter about it.

Romney is apparently Trump’s target of the week and this is what his is saying about him:

Trump called him “pathetic”

“@ChatteringTeef: @BornToBeGOP @realDonaldTrump @MittRomney hates to see Trump’s success when he was so pathetic

Trump said Romney is jealous of him

“@classyexplorer: @ahernandez85a Romney is a pawn of the Establishment and has no individual thought process. He is jealous of Trump!”

— Donald J. Trump (@realDonaldTrump) February 25, 2016

Trump said Romney “cowered” against Obama

“@conservativevin: @ahernandez85a Romney should have been a tough guy with Obama. He cowered and lost. BADLY! He’s not relevant!”

What is the fight about you might ask? Romney said he has a good reason to believe there is a bombshell in Trump’s taxes and asked him to show them:
