Six Republican presidential candidates took to the debate stage Saturday night in Greenville, South Carolina, and it was anything but boring.

On the heels of the death of Supreme Court Justice Antonin Scalia, the candidates said President Barack Obama should not fill the vacancy. "I think it's up to [Senate Majority Leader] Mitch McConnell and everybody else to stop it," Donald Trump said. "It's called delay, delay, delay."

There were a number of heated exchanges throughout the evening. Former Florida Gov. Jeb Bush argued with Trump over foreign policy. Later in the night, Trump called Sen. Ted Cruz (R-Texas) "the single biggest liar" after Cruz accused Trump of supporting taxpayer funding for Planned Parenthood.
