Political analysts and observers sharply criticized President Donald Trump's comments to reporters on Sunday evening.

Trump was asked whether his administration had begun revoking visas of foreign travelers who celebrated the death of conservative activist Charlie Kirk last week. Trump said officials are"looking at names" and that Republicans wouldn't celebrate if a Democratic activist were killed.

"That's not right," Trump said. "We wouldn't celebrate if something happened like this, and we don't. These are sick people. These are really derranged people."

Commentators and observers replied to Trump's comments on social media.

"He's a disgrace," author John Pavlovitz posted on X.

"Trump mocked Paul Pelosi getting attacked," Democratic activist Harry Sisson posted on X. "He’s a total liar."

"Trump is absolutely delusional," political commentator and entrepreneur Ed Krassenstein posted on X. "He is gaslighting you. Tell Melissa Hortman’s family that there’s no hate or violence on the right. Tell Paul Pelosi that!"

"Does Trump think everyone forgot when he mocked Paul Pelosi being attacked?" Republicans Against Trump posted on X.

Kari Lake, the Trump administration's senior advisor for the U.S. Agency for Global Media, claimed during conservative activist Charlie Kirk's memorial service at the Kennedy Center on Sunday that college "indoctrination camps" had radicalized Kirk's shooter.

Kirk's memorial service was attended by several members of President Donald Trump's cabinet, including Health Secretary Robert F. Kennedy Jr. and Director of National Intelligence Tulsi Gabbard.

"How does a 22-year-old become so filled with hate?" Lake said during her speech. "Five years earlier, I was told he was a Trump supporter."

"Then we send our kids off to college and they brainwashed him," she continued. "I am making a plea to mothers out there, please don't send your children into these indoctrination camps."

"At one point, that 22-year-old was a baby in his mother's arms," Lake continued. "And by all accounts, they did a good job raising him until he was sent off to be brainwashed."

"We are living through the most horrific brainwashing campaign in the history of mankind," she added.

Lake's comments come at a time of intense debate about Kirk's assassination. Rightwing figures have blamed Democrats for Kirk's assassination, and Democrats have rejected those claims.

Lake also called on both sides to work to end political violence.

"I'm not going to say our side is perfect, but damn it, this is coming from the other side!" Lake said.

President Donald Trump blamed former President Joe Biden in a social media post for what he called a "terrible" murder that occurred in Dallas over the weekend.

"I am aware of the terrible reports regarding the murder of Chandra Nagamallaiah, a well-respected person in Dallas, Texas, who was brutally beheaded, in front of his wife and son, by an ILLEGAL ALIEN from Cuba who should have never been in our Country," Trump posted on Truth Social on Sunday night.

Nagamallaiah was a hotel employee in Dallas who was brutally murdered by one of his co-workers in a dispute over a broken washing machine, according to court documents published by CBS News.

A 37-year-old suspect has been arrested in the case, according to media reports.

The timestamp on Trump's post shows it was published during the memorial service for conservative activist Charlie Kirk at the Kennedy Center.

"This individual was previously arrested for terrible crimes, including child sex abuse, grand theft auto, and false imprisonment, but was released back into our Homeland under incompetent Joe Biden because Cuba did not want such an evil person in their Country," Trump's post continued.

"Rest assured, the time for being soft on these Illegal Immigrant Criminals is OVER under my watch!"
