Presidential nominees took to Twitter to issue their first statements following the horrific Orlando nightclub shooting that left 50 people dead early Sunday morning.

While offering his condolences to the victims and their families, Presumptive Republican nominee Donald Trump called for toughness and vigilance.

He then posted a tweet saying he was right about “radical Islamic terrorism” but did not want his supporters to congratulate him.

Presumptive Democratic nominee Hillary Clinton was more reserved in her response and said that her thoughts were with those affected by the shooting.

Meanwhile, Vermont Senator Bernie Sanders, who remains in the race for the Democratic nomination, called the shooting "horrific" and "unthinkable” and said it underscores the need for gun control measures.
