Just one day after giving his controversial speech at the United Nations General Assembly, President Donald Trump came under fire once again for citing a nonexistent African country during a meeting with several leaders in the region. In response, the president was quickly trolled, including from the host of "The Late Show" Stephen Colbert.

Colbert on Trump

In the over two years that Donald Trump has been an official politician, he's often found himself facing criticism for a variety of reasons. Trump's unorthodox style and inflammatory rhetoric usually results in the majority of the mainstream media and his critics lashing out, with many publicly hitting back at the former host of "The Apprentice" in the process.

Since his election win over then Democratic nominee Hillary Clinton last November, Trump's only increased the controversy surrounding him, which has included, but hasn't been limited to, his outbursts on social media and during speeches and interviews. On Tuesday, Trump took part in his first United Nations General Assembly, which he was instantly criticized after threatening potential war with North Korea, while also mocking Kim Jong-un as "Rocket Man." After 24 hours of backlash, Trump found himself in hot water a second time after meeting with a group of African leaders, which was highlighted during the September 20 edition of "The Late Show" on CBS.

Kicking off the Wednesday edition of "The Late Show," host Stephen Colbert made sure to bring up Donald Trump's lunch with African leaders at the United Nations, specifically his blunder about name-dropping the nonexistent country of "Nambia" during his speech.

"The U.N. is in town this week," Colbert said. "Today Donald Trump hosted a lunch with African leaders and began his speech with a creative list of those countries," Colbert added, before running a video clip where the president praised the health care system of "Nambia."

"Now there is no such country as Nambia," Stephen Colbert said, while noting, "despite that, they will soon have a better health care system than we do." "I might move to Nambia," he continued with sarcasm, adding, "I hear very good things." "He went on to praise the African republics of Nambla, Wango Tango, and Waconda," Colbert continued to the laughter of the audience.

While comedians, social media critics, and late-night talk show hosts continue to have fun with Donald Trump's mistakes, the president has more serious issues to worry about. In addition to the global challenges facing the White House, Trump is dealing with a fight over the future of the Affordable Care Act, in-fighting within his own Republican Party, and an approval rating that is below 40 percent.
