After the Democratic presidential debate earlier this month, the Republicans had their third presidential debate on Wednesday. The Republican debate among the ten candidates was reported to be nasty.

We’ve listed the six most awkward moments that happened in the heated debate.

1. Bush vs. Rubio

The Washington Post reported that at the beginning of the debate, former Florida Gov. Jeb Bush immediately attacked Florida Sen. Marco Rubio for his number of absences. Bush said, “This was a six-year term. You should be showing up for work.”

However, Rubio backfired and told him, “someone has convinced you that attacking me is going to help you. It’s not.”

He added, “I’m not running against Gov. Bush. I’m not running against anyone else on the stage. I’m running for president.”

2. Debate Moderators were Mocked

New Jersey Gov. Chris Christie and Texas Sen. Ted Cruz both criticized the moderators. Cruz mentioned that the moderators were asking “too negative” questions while Christie said they were focusing themselves on “fantasy football.”

At one point, Christie even lashed out at moderator John Harwood and said, “Do you want me to answer, or do you want to answer? Even in New Jersey, what you’re doing is called rude.”

3. Kasich vs. Carson

Ohio Governor John Kasich slammed the tax plans, as mentioned by CBS News. He called candidate Ben Carson’s plan a “fantasy.”

Kasich said, “You can’t do it with empty promises. You know, these plans would put us trillions of dollars in debt. We cannot elect somebody that doesn’t know how to do the job.”

Vox noted that Carson did not participate much at the debate.

4. Trump vs. Kasich

The moderators then grilled billionaire businessman, Donald Trump, on his tax plans.

Kasich said, “You know these plans would put us trillions and trillions in debt. Why don’t we just put a chicken in every pot while we’re coming up with these fantasy tax games?”

Trump, who gave his view on gun laws, then got back at Kasich. He pointed that Kasich was then the managing director at the Lehman Brothers.

He then told Kasich, “such a nice guy…but then his poll numbers tanked. That’s why he’s on the end, and he got nasty, and he got nasty.”

5. Hillary Clinton is a “Liar”

Even though it was a Republican debate, Democratic frontrunner Hillary Clinton was mentioned. Rubio called the former Secretary of State a liar. The media covered her falsehoods, said Rubio.

Clinton told The Hill in a text, “Seems to me: 10 candidates. 0 new ideas.”

6. Graham’s Big Confession

NBC News noted that South Carolina Senator Lindsey Graham said, “At the end of the day folks, I am trying to solve a problem and win an election. I’m tired of losing.”
