The Republican presidential front-runner repeatedly tweeted and retweeted messages critical of Sen. Lindsey Graham (R-South Carolina) and former New York Gov. George Pataki (R).
Both Graham and Pataki used their lower-tier debate opportunity to rip into Trump's plan to temporarily bar Muslims from entering the US.
Trump responded on Twitter, sharing messages saying Pataki needs a "brain surgeon" and that Graham is "weak," among other insults.
See some of Trump's responses below:
