Elon Musk's influence in global affairs has some officials worried, The Washington Post reported.
Musk has kept in touch with foreign officials while staying away from Washington, per the Post.
Musk has publicly met with Russian President Vladimir Putin, Brazilian President Jair Bolsonaro, and other foreign leaders, raising conflict of interest questions.
Government officials have bolstered Musk's competitors in an effort to reduce their reliance on his businesses, the Post report said.
The Post report notes, however, that there is still a large interest from the US government to work with Musk.
