Jimmy Kimmel isn't backing down.

On April 28, the late-night host mocked President Donald Trump's demand for him to be fired for jokingly calling first lady Melania Trump an "expectant widow" on his show last week. He also accused the president of hypocrisy, suggesting Trump made a very similar joke about himself.

In his latest monologue, Kimmel showed a clip of Trump, while welcoming King Charles III, noting that his parents were married for 63 years and telling the first lady he will not live long enough for them to surpass that. "That's a record we won't be able to match, darling," Trump said. The president and the first lady have been married for 21 years.

"Wait a minute. Did he just make a joke about his death?" Kimmel asked. "He should be fired for that! Only Donald Trump would demand I be fired for making a joke about his old age, and then a day later, go out and make a joke about his own old age!"

As he continued his monologue, Kimmel dismissed the "ridiculous" people making a "big thing out of this joke" he made.
