Two firefighters were arrested on Wednesday while they were responding to the Bear Gulch fire in Washington state's Olympic National Forest, the Seattle Times reported. Now the state's senator is demanding "immediate answers."

"This administration’s immigration policy is fundamentally sick. Trump has wrongfully detained everyone from lawful green-card holders to American citizens – no one should assume this was necessary or appropriate,” said Sen. Patty Murray (D-WA) in a statement.

It's unknown why the two firefighters were arrested, and immigration officials haven't indicated why or their identities. ICE has been arresting people across the country regardless of their citizenship status. There are multiple reported cases of immigrants who have Green Cards and whose paperwork is in order, and there are citizens who ICE has arrested.

Murray blasted Trump for "decimating" the U.S. Forest Service with staff and budget cuts, noting it adds to the burdens for firefighters, The Guardian cited.

"What’s next? Will Trump start detaining immigrant servicemembers? Or will he just maintain his current policy of deporting Purple Heart veterans?" Murray asked.

“I am demanding immediate answers from this administration about the circumstances of this incident, the whereabouts of the detained firefighters, and the administration’s current policy regarding immigration enforcement during active wildfires," she added.
