Donald Trump criticized Republicans Tuesday, tweeting that they "may be the worst negotiators in history."

The billionaire real estate mogul's harsh words for the GOP concerned the last-minute fiscal cliff deal, which was brokered by Vice President Joe Biden and Senate Minority Leader Mitch McConnell (R-Ky.) late Monday night. Trump -- a Republican who's not shy about criticizing Democrats or President Barack Obama -- said "Republicans got nothing" in the deal.
