Mitt Romney's Aide Loses Temper

It was an explosive moment as a top Mitt Romney aide, traveling press secretary Rick Gorka, lost his temper with reporters.

The off-camera outburst was caught on audio.

"Kiss my [expletive]!" said Gorka.

He also told reporters to "Shove it."

Now, the incident is becoming an embarrassment for the Republican presidential candidate.

"Some very tense moments between the press pool and the Romney campaign," said Good Morning America's David Muir.

"You're starting to see some of the Romney campaign frustrations spill out," said Jan Crawford on CBS This Morning.

The blow-up happened during Romney's visit to Poland. It's the latest stop on a foreign tour that some say has been dogged by blunders.

In the Polish capital, Warsaw, Romney visited the Tomb of the Unknown Soldier.

After shaking hands with local dignitaries, Romney walked to his car, ignoring questions shouted by U.S. reporters.

"What about your gaffes?" yelled one reporter.

That's when Gorka lost it.

"Show some respect," said Gorka.

"We haven't had another chance to ask him questions," said another reporter.

"Kiss my [expletive]! This is a holy site for the Polish people. Show some respect. Unbelievable," said Gorka.

"Shove it. Shove it," said Gorka.

That's right—he said "shove it" and "kiss my [expletive]" at a site that he himself described as a holy place!

Gorka later called reporters to say he lost his cool and to apologize, calling his comments "inappropriate."
