A Fox News host slammed President Barack Obama for getting emotional during his speech announcing executive actions to curb gun violence, and even suggested that the president used "a raw onion" to produce fake tears.

Obama delivered an emotional White House speech to roll out his executive order to expand background checks and gun safety measures on Tuesday. With tears streaming down his face, he condemned the widespread of gun violence across the U.S. and promised to take against to reduce it with or without support from Congress.

"In this room right here, there are a lot of stories. There's a lot of heartache," said Obama while standing in the East Room with relatives of victims who were shot in mass shootings. "There's a lot of resilience, there's a lot of strength, but there's also a lot of pain."

The president was overcome with emotion when he began talking about the 2012 Sandy Hook Elementary School massacre, which led to the deaths of 20 first-grade students.

"Every time I think about those kids, it gets me mad," he said, wiping away tears. "And by the way, it happens on the streets of Chicago every day."

Later that day, conservative commentator Andrea Tantaros questioned whether or not Obama was being authentic while he was tearing up during his press conference.

"I would check that podium for like a raw onion or some no-more-tears," said Tantaros on Fox News' "Outnumbered." "I mean, it's not really believable."

She went on to argue that the president should have spoken out about gun violence and paid visits to Chicago earlier in his presidency.

"If he really cared about an issue, especially like Chicago in his hometown, and it was plausible, he'd be doing something very different than he's doing, and he would have spoken out a long time ago," Tantaros said.

"He's almost at the end of his term, and you haven't heard him go to Chicago and really speak out about this issue, and he's uniquely poised to do so really. But everything he's doing won't solve the problem."

The other Fox News contributors were also very critical of Obama's display of emotion.

"What was really upsetting was the tears that he wiped away again and again," said co-host Melissa Francis, claiming that Obama is only visibly moved by gun violence rather than terrorism.

"I mean, we feel frighten about what's going on with ISIS. And he can't pull that kind of passion for anything about this."

Likewise, co-host Meghan McCain, the daughter of Sen. John McCain, R-Ariz., said the speech "didn't seem horribly authentic." She also likened the president's tears to "bad political theater."
