Donald Trump is not happy with his microphone and he is not afraid to express it.

During a crowded rally held in Pensacola, Florida, The Donald stopped mid speech and went on a rant, deriding the stadium's sound personnel or "mic guy."

Trump said, "I don't like this mic, whoever the hell brought this mic system, don't pay the son of a b**** who brought it in," inciting laughter and applause from the crowd. However, Trump legitimately look annoyed.

He further continued his expletive-filled tirade and repeatedly said that the mic he is using is terrible and keeps on popping. He went on to call the mic guy a "son of a b****" again, before proceeding to say that he will not pay for it.

He reasoned that although he believes in paying employees, he reiterated that when an employee does a bad job, he does not have to be paid and said that employers need to be tough with their people -- or else they do subpar job, Mashable reported.

According to Business Insider, reporters who covered the rally said that they had difficulty understanding Trump's speech, and this time, it's the mic's fault.

This is not exactly the first time that The Donald expressed frustration during a campaign, as he was known to engage with his hecklers and political opponents.

Before his tirade, Trump was pandering to the crowd and proudly declared that he will win the State of Florida. He then said, "I am kicking a** in Florida," which garnered a positive reaction from the crowd. In addition, the mogul-turned-politician once again took a jab to his GOP rivals, particularly Jeb Bush and Marco Rubio.

He proceeded to call Jeb "low energy" once again, and also Rubio, who's currently a senator in the state, ABC News has learned.

Trump also took a dig on Ted Cruz's citizenship and said that if the Supreme Court ends up ruling that he can't run, he suggested that Cruz needs to concede the election to Hillary Clinton.

The billionaire candidate also seems to enjoy insulting his way into the campaign and even called Democratic candidate Bernie Sanders "crazy Bernie." Trump then continued to say that he does not know whether he wants to run against Hillary or Sanders more.

Ted Cruz on the other hand, repeatedly brushed aside Trump's comments regarding his citizenship, as he cited that he has an American mother, making him eligible for the presidency.
