Tesla boss Elon Musk has pledged to "significantly" cut back his role in the US government after the electric car firm reported a huge drop in profit and sales for the start of this year.
Musk has led the newly created advisory body - the Department for Government Efficiency (Doge) - since last year, putting the world's richest man at the heart of cutting US spending and jobs.
But Musk said his "time allocation to Doge" would "drop significantly" from next month, adding he would spend only one to two days per week on it "as long as the president would like me to do so and as long as it's useful".
His political involvement has sparked protests and boycotts of Tesla cars around the world.
On Tuesday, the firm reported a 20% drop in car sales for the first three months of the year, compared with the same period last year, while profits fell more than 70%.
The company warned investors that the pain could continue, declining to offer a growth forecast while saying "changing political sentiment" could meaningfully hurt demand.
The tech boss contributed more than a quarter of a billion dollars to Trump's re-election and his political involvement has sparked protests and boycotts of Tesla around the world.
He blamed the "blowback" on people who would "try to attack me and the Doge team". But he called his work at Doge "critical" and said "getting the government house in order is mostly done".
Trump's tariffs on China also weighed heavily on Tesla. Although the vehicles Tesla sells in its home market are assembled in the US, it depends on many parts made in China. "Rapidly evolving trade policy" could hurt its supply chain and raise costs, according to the company.
"This dynamic, along with changing political sentiment, could have a meaningful impact on demand for our products in the near-term," Tesla's quarterly update said.
Musk has clashed on trade with other Trump administration figures, including trade adviser Peter Navarro.
On Tuesday, Musk said he thought Tesla was the car company least affected by tariffs because of its localised supply chains in North America, Europe and China, but he added that tariffs were "still tough on a company where margins are low".
"I'll continue to advocate for lower tariffs rather than higher tariffs but that's all I can do," he said.
Earlier this month, he called Navarro a "moron" over comments he had made about Tesla. Navarro had said Musk was "not a car manufacturer" but a "car assembler, in many cases".
"I think Elon is not someone who surrounds himself with a great diversity of opinion to challenge his thinking, he's a pretty single-minded individual," added Mr Ell, who is now chief executive of translation software firm Phrase.
Tesla said artificial intelligence would contribute to future growth, though investors have been unconvinced by such arguments in the past.
Shares in the company had shed about 37% of their value this year as of market close on Tuesday. They rose by more than 5% in after-hours trading following the results.
The firm faces fierce competition, Mr Coatsworth said, warning that potential disruption to global supply chains as a result of Trump's trade war also created risks.
"Tesla's problems are mounting," he said.
