Musk makes a rare appearance in a suit at Congress, unexpectedly warned for using his phone

On Tuesday night, Musk attended Trump's speech at the U.S. Congress. Musk took off his usual T-shirt and jeans and put on a suit.

Previously, Ukrainian President Zelensky was criticized for not wearing a suit during his meeting with Trump at the White House. Musk rarely wears suits and ties, he even once wore a black T-shirt that read "Occupy Mars" while answering questions at the White House. Despite being appropriately dressed, he was asked by security to put away his phone because he was using it to record video.

Later, Trump praised Musk's efforts to reduce government spending, and Musk saluted the members present with a smile.
