GOP Rep. Upton shares threatening voicemail after infrastructure vote

Republican Rep. Fred Upton (Mich.) on Monday revealed a threatening voicemail he received after voting for the infrastructure bill, according to a recording played during an interview with CNN's Anderson Cooper.

Driving the news: In the recording, a caller said: "I hope you die. I hope everybody in your f--king family dies," and also called Upton a "f--king piece of sh-t traitor," per CNN.

• Upton was one of 13 House Republicans who crossed party lines to help Democrats pass the $1.2 trillion infrastructure bill last week.
• "I regret that this good, bipartisan bill became a political football in recent weeks. Our country can't afford this partisan dysfunction any longer," Upton wrote in a tweet after the infrastructure vote.

The big picture: Upton was also one of 10 House Republicans who voted to impeach former President Trump in January.

What he's saying: "I'll tell you it's a terrible way — we have seen civility really downslide here. I'm concerned about my staff. They are taking these calls," Upton told Cooper.

• "These are very disturbing, adult language ... To say the least, that truly is frightening."
