President Biden has a short temper and frequently lashes out at staff members with profanity-laden rants if they do not meet his expectations, according to a new Axios report.

One official in the administration told the outlet that "no one is safe" from Biden's wrath. Aides are reportedly known to meet with him in groups of two or more to diffuse potential tension.

Some of the president's go-to attacks include, "How the f--- don't you know this?" and "Don't f---ing bulls--- me!"

Aides have framed his outbursts as a desire for accuracy and competence, telling the outlet that many see getting shouted at by the president as a rite of passage.

"If there is something that's not in the brief, he's going to find it," said Ted Kaufman, Biden's chief of staff when he was in the Senate. "It's not to embarrass people, it's because he wants to get to the right decision. Most people who have worked for him like the fact that he challenges them and gets them to a better decision."

The White House did not immediately respond to a request for comment from Fox News Digital.

It is not the first time reports from within Biden's circle have undermined his carefully curated "Uncle Joe" public persona. Biden last showed his darker side when a hot might caught him calling Fox News White House correspondent Peter Doocy a "stupid son of a b----."

Monday's report comes as Biden is facing criticism from conservatives who say his latest gaffe revealed sensitive U.S. military information to global adversaries.

Biden defended his administration's decision to send cluster munitions to Ukraine in a Sunday interview, framing it as a "transition period" until more munitions are produced.

"This is a war relating to munitions. And they’re running out of that ammunition, and we’re low on it," Biden told CNN's Fareed Zakaria. "And so, what I finally did, I took the recommendation of the Defense Department to – not permanently – but to allow for this transition period while we get more 155 weapons, these shells, for the Ukrainians."

"Joe Biden broadcasting to the world that the US is low on 155mm shells," conservative communicator Steve Guest tweeted. "Moron. Does Biden not care that our adversaries in China are listening?"

The White House responded to the criticism by saying the U.S. and its allies "will have much higher production levels soon."

A 25-year-old man is in custody after Chinese officials said he entered a kindergarten with a knife on Monday morning and killed six people, including children and adults.

Police said one other victim was wounded on Monday when the suspect, who authorities only identified as a man from Lianjiang with the surname Wu, began his assault at a kindergarten in Lianjiang, a city in the Guangdong province, at approximately 7:40 a.m. local time.

Local media reported at least one of the deceased victims is a child and one is a teacher.

Chinese outlet Dafeng News reported the attack may have been in response to a vehicular incident outside the school as an unidentified witness said they saw a car strike the attacker’s child prior to the attack. The driver of that vehicle is among the deceased, the outlet reported.

Videos allegedly from the attack surfaced on Weibo, China’s largest social media website, prompting outrage from users. One video showed a man carrying a knife walking past the kindergarten’s playground. A separate video showed several victims bleeding outside the school.

Within hours of the attack the topic was trending and the discussion amassed over 290 million views, Reuters reported.

"It's outrageous to do this to children who have no power at all. How many families will be destroyed by this ... I support the death penalty," one user on the platform said.

Another added: "Why do such cases still continue to emerge?"

While China observes strict gun laws, the country has experienced several kindergarten stabbings in recent years.

In August 2022, a stabbing at a Jiangxi kindergarten left three victims dead and six others wounded, Reuters reported.

In 2021, another stabbing attack at a Guangxi kindergarten left two children dead and 16 wounded.

In 2020, a school guard was accused of injuring 39 people with a knife.

Another attack in 2017 featured a man using an explosive device outside a Jiangsu kindergarten, which left him and a few others dead. Dozens were also wounded.

Chinese authorities have said many of these crimes are personal, are usually carried out with knives or homemade explosives, and are often attributed to neurological disorders or other mental health problems, Reuters reported.
