The mayor of Portland was teargassed by federal agents during protests against the presence of the agents sent by Donald Trump to quell unrest in the city.
Ted Wheeler, the Democratic mayor of the city in Oregon, said it was the first time he had been teargassed.
Protesters had lit a large fire and armed agents launched teargas and stun grenades into the crowd.
Wheeler was mostly jeered by demonstrators who have clashed nightly with federal agents.
The mayor has opposed the federal agents’ presence, but has faced harsh criticism for not taking more action to protect citizens.
