Elon Musk wore funny T-shirts and hats to the White House, not a suit and tie like other important people.
He didn't dress like the president's friends, wearing things like a 'Dogefather' shirt instead.
His casual clothes showed he was different, but some people didn't like it, and it became part of a big problem.
Wearing those clothes might have helped him in his tech work, but it didn't work well in politics.
