As President Joe Biden touted a move toward electric vehicles and the need to “buy American,” Elon Musk took the opportunity to point out that Tesla (TSLA) is the most American-made car in the country with some subtleties that he hoped wouldn’t go unnoticed by the administration.

In June, Tesla’s Model 3 took the top spot in’s American Made Index, marking the first all-electric car to top the list in its 16-year history of ranking vehicles.

The annual survey ranks new vehicles based on U.S. factory jobs, American manufacturing plants, and sourcing of parts in the U.S., said.

Musk’s comments came in response to a tweet from Biden, who posted, “We’re making 'buy American' a reality — not just a promise.”

Musk, who has been feuding with Biden because he has refused to acknowledge Tesla’s participation in the electric vehicle market, responded to the president’s Twitter post with an article from USA Today that mentioned Tesla as the top American-made carmaker as part of the survey.

His post also included the comment, “[ahem]” as if to remind the president that Tesla existed.

Musk followed the Twitter post with a second post six hours later that read, “Model 3 is literally the most made in America car in – well of course – America,” to help drive home his comments to the president.

Both posts tagged Biden and were in response to Biden’s initial tweet.

Musk has been critical of Biden’s comments on the EV market as he has called the president a “damp sock puppet in human form” on Twitter after he praised GM and Ford in a video, saying they were producing more electric vehicles in the U.S. than ever before, but failing to mention Tesla.

In another tweet, Musk reminded Biden that Tesla “Starts with T, Ends with A, ESL in the middle.”

Biden did mention Tesla in a speech as he called the automaker, “our nation’s largest electric-vehicle manufacturer." Musk responded on Twitter with a smiling sunglasses emoji.

Tesla took top rankings in’s survey as the Model 3, as well as its Model Y, are produced in Fremont, California.

While the Model 3 was at the top of the list for 2021, this is not the first time that Tesla has made it on the ranking. In 2020, its Model 3 took the No. 4 spot and Model S achieved the No. 3 spot, and its Model X placed No. 9 for the year.

As of Thursday at 9:30 a.m. EST, shares of Tesla were trading at $912.57, down $10.82, or 1.17%.
