UAW files labor charges against Trump and Musk over strike remarks

Driving the news: The UAW said it filed the charges against Trump and Musk "for their illegal attempts to threaten and intimidate workers who stand up for themselves by engaging in protected concerted activity, such as strikes."

• The union flagged this comment by Trump: "You walk in, you say, You want to quit? They go on strike, I won't mention the name of the company, but they go on strike and you say, That's OK, you're all gone. You're all gone. So, every one of you is gone."
• It's illegal to threaten to fire workers for going on strike or to actually do so, the union noted.
• Musk, who has endorsed Trump, laughed at the Republican presidential nominee's comments but didn't directly address his remarks.

What they're saying: "Both Trump and Musk want working class people to sit down and shut up, and they laugh about it openly," UAW president Shawn Fain said in a statement. "It's disgusting, illegal, and totally predictable from these two clowns."

• Musk did not respond to a request for comment on Tuesday.

• Trump campaign senior adviser Brian Hughes called it a ""frivolous lawsuit" and "a shameless political stunt intended to erode President Trump's overwhelming support among America's workers."

What's next: When labor charges are filed, the National Labor Relations Board decides whether to investigate the allegations. If it concludes there were violations, it could impose penalties.
