Republican frontrunner Donald Trump turned to Twitter Friday night to target a handful of conservatives who have openly criticized his campaign as of late.
Trump, who has become known for his online tirades, first took aim at his favorite target: 2016 rival Jeb Bush.
The billionaire businessman then targeted Media Research Center founder Brent Bozell and Glenn Beck. Both contributed to the National Review's special edition "Against Trump" issue published the night before.
Trump then turned his ire to Texas Sen. Ted Cruz who he is locked in a dead heat with in Iowa.
While neither Beck, Bozell or Cruz fired back any responses online, Bush took advantage of the opportunity, tweeting a photo of his mother Barbara Bush wearing football pads.
"I'd be careful, Donald," he joked.
