South Korea's President Yoon Suk-yeol is facing criticism after his comments regarding U.S. President Joe Biden went viral yesterday.

Biden was in New York on Wednesday at the United Nations General Assembly, where he committed $6 billion to the Global Fund to AIDS, Tuberculosis, and Malaria.

From Biden:

And over the past 20 years, through our work together, it's estimated that the Global Fund has saved, as you heard before, 50 million lives and dramatically — dramatically reduced the death rate of HIV, tuberculosis, and malaria in the countries where it's working.

The promise of $6 billion, however, requires congressional approval, which President Yoon noted on a hot mic.

"How could Biden not lose damn face if these f***ers do not pass it in Congress?" Yoon was caught saying to his aides afterwards in footage that went viral in South Korea.

Here is video of the comment (in Korean):

President Yoon has been widely criticized since being elected in May and currently stands at only a 32% approval rating.

A YouTube video of Yoon's comments racked up over two million views just hours after it was posted, and "f***ers" became the number one trending topic on Twitter in South Korea on Thursday.

"The president's words and actions are the national dignity of the country," one YouTube commenter wrote.
