Donald Trump has once again angered many celebrities.

On Saturday, the president of the United States (POTUS) took to Twitter to slam Carmen Yulin Cruz, mayor of San Juan, Puerto Rico, over her "nasty" comments against him. Trump criticized her "poor leadership skills" and accused her of "[wanting] everything to be done for them when it should be a community effort."

Trump's series of tweets against Cruz did not go unnoticed among several celebrities, who were quick to pinpoint his flaws as POTUS. "Trump continues to dominate the [worst] president ever competition," John Legend wrote.

Chris Evans also joined in and criticized Trump's attitude as a leader in times of crisis. The "Captain America: Civil War" star stressed that the POTUS is being narcissistic, defensive and insulting. Evans also added that Trump made multiple references to himself in the third person.

On the other hand, Cher believed that Trump attacked Yulin because "he's never known hunger, thirst, dirt, no phone, or watch a sick child die 4 lack of meds." Meanwhile, Lady Gaga took a jab at the president by saying that "it's clear where the 'poor leadership' lies."

This is not the first time that celebrities have bashed Trump for his words and actions. Legend and Evans did the same when Trump claimed that he waited for facts before he released a statement on the white nationalist demonstration in Charlottesville, Virginia in August. Many stars criticized Trump for taking two days to condemn white supremacists and hate groups like KKK in a protest that resulted in one casualty and injured 20 others.

"One of the most transparent lies Trump told today is that he likes to wait for the facts before he makes a statement. Hahahahahaahaha," Legend wrote on Twitter. "Seriously. EVERYONE needs to watch that press conference in its entirety. He does everything flawlessly wrong. It's a stunning disaster," Evans wrote.

Meanwhile, aside from Trump's celeb critics, "Hamilton" writer Lin-Manuel Miranda, a Puerto Rican, also wrote series of tweets about Trump. Miranda compared Cruz and Trump's leadership by citing that the former is hard at work in aiding her fellow citizens while the latter is busy playing golf.
