Republican presidential hopefuls Govs. Jeb Bush and Chris Christie say Florida Sen. Marco Rubio, hasn't been tested in a way that the governors running for president have, leaving him unqualified to be president.
Speaking to MSNBC's Morning Joe Monday in New Hampshire, which is set to host the country's second nomination contest Tuesday, Bush referred to Rubio as "a bright, charismatic leader" but described his leadership skills as a "work in progress."
Christie, New Jersey's sitting governor, repeated accusations that Rubio recites the same campaign points, calling him a "talented guy" when required to "deliver a speech, read a teleprompter."
Bush, Florida's former governor, also attacked billionaire Donald Trump, with whom he clashed at Saturday's GOP debate over the issue of eminent domain, calling him a "loser."
