Republican presidential candidate Donald Trump fired back at South Carolina Gov. Nikki Haley over the thinly veiled jabs she took at the GOP front-runner while delivering the GOP response to the State of the Union (SOTU) address Tuesday night.

The Republican governor took several swipes at Trump, urging Americans to resist "the siren call of the angriest voices" during her party's formal response to President Barack Obama's SOTU speech.

"During anxious times, it can be tempting to follow the siren call of the angriest voices. We must resist that temptation," Haley said. She also argued that the U.S. should continue admitting "properly vetted legal immigrants, regardless of their race or religion" -- a direct reference to Trump's proposal to ban Muslims entering the U.S.

"No one who is willing to work hard, abide by our laws, and love our traditions should ever feel unwelcome in this country," she said.

When asked if she was referring to the billionaire businessman in her speech, Haley admitted that Trump was one of the people she was singling out.

"He was one of them, yes," Haley said Wednesday morning on NBC's "Today" show. "Mr. Trump has definitely contributed to what I think is just irresponsible talk," added Haley, who is rumored to be a top pick for the Republican vice presidential nomination.

In response, Trump shot back at the South Carolina governor, calling her "weak" on illegal immigration.

"She's weak on illegal immigration, and she certainly has no trouble asking me for campaign contributions, 'cause over the years she's asked me for a hell of a lot of money in campaign contributions. So, you know, it's sort of interesting to hear," he said on "Fox and Friends."

He also suggested that she would be petitioning him for campaign donations if he were not running for president.

"Perhaps, if I weren't running she'd be in my office asking for money. But now that I'm running, she wants to take a weak side on immigration," he said.
