Donald Trump's never been known to mince words, nor to care about conventional wisdom. And now that the Donald has become a power broker in the GOP, he's had a lot of opportunities to put his blunt, confrontational style to work in attacking rivals of his chosen candidate, Mitt Romney.

However, probably no one has been hit as hard by the Donald's acid tongue as Rick Santorum. For instance, after the former Senator's surprise wins in Colorado, Missouri and Minnesota, Trump scoffed at him as though he hadn't won anything, comparing him to a student who failed out of high school, yet wants to go to the Wharton School of Finance (a school of which Trump himself is an alumnus).

And now, Trump is calling the actions of all the Republican candidates -- especially Santorum -- "disgraceful" in that they are still trying to contest Romney's march to the nomination. Mediaite caught the Donald's caustic remarks on Fox and Friends this morning:

It’s not game over because nobody gets out. I mean, Rick Santorum, who lost by 18 or 19 points running for the Senate in Pennsylvania, just keeps going and going… what does he have to lose by staying in? So he just doesn’t get out. At a certain point, you have to get behind a person and you have to start going after Obama, not each other. And what the Republicans are doing is disgraceful.
