Before he was the world’s richest man, Elon Musk was never been very shy about commenting on politics or public policy. He has also been keen not to mince words about how his feelings toward President Joe Biden. In Musk’s view, Biden has left a lot to be desired.

Speaking Monday night at the All-In Summit in Miami, Musk lambasted Biden for what he asserted was a lack of any achievements throughout the course of his barely two-year-long presidency.

Musk contrasted the Biden administration unfavorably with the former President Donald Trump’s administration, which he said was more inclined to take action.

“This administration, it doesn’t seem to get a lot done,” Musk said. “The Trump administration, leaving Trump aside, there were a lot of people in the administration who were effective at getting things done. This administration seems to not have the drive to just get [expletive] done. That’s my impression.”

Musk has been frequently critical of Biden and congressional Democrats throughout the last year.

During congressional debates over the size of Biden’s proposed Build Back Better spending plan, a massive multi-trillion dollar social and climate plan, Musk railed against Democrats for their plans to raise taxes on wealthy citizens like himself. He also went on to spar over Twitter with left-leaning senators like Elizabeth Warren of Massachusetts and Bernie Sanders of Vermont.

Musk has also butted heads with Biden himself. Last September, Musk fumed over Biden extending an invitation to the White House for automakers but not Tesla. After launching a lawsuit against the Securities and Exchange Commission in February, Musk alleged that the Biden administration was looking to harass him over criticism of the White House.

Musk's invectives against Biden have also at times taken on a crude tone. In January, Musk wrote on Twitter that the president was a “damp sock puppet in human form.” At the All-In Summit, Musk went on the attack again.

“The real president is whoever controls the teleprompter. The path to power is the path to the teleprompter. I do feel like if somebody were to accidentally lean on the teleprompter, it’s going to be like Anchorman,” Musk remarked, referring to the 2004 comedy film about a news anchor who injudiciously would read anything on the teleprompter.

Musk's tensions with Biden come at a time when the White House has faced criticism from Jeff Bezos, who is also among the richest people in the world. The former Amazon CEO has been critical of Biden's economic policy with inflation, while Biden's team has noted that Bezos has benefited from an unfair tax system.
