In the voicemail, which Upton played during an interview with CNN’s Anderson Cooper on “AC360,” a caller told the Michigan Republican: “I hope you die. I hope everybody in your f**king family dies,” while labeling him a “f**king piece of sh*t traitor.”

Upton was one of just 13 House Republicans who voted with Democrats on Friday to pass the $1.2 trillion infrastructure bill after hours of delays and debating among Democrats. The legislation, which passed the Senate in August, will deliver $550 billion in new federal investments in America’s infrastructure over five years, including roads, bridges, mass transit, rail, airports, ports and waterways.

Following the Friday vote, Upton tweeted in part, “I regret that this good, bipartisan bill became a political football in recent weeks. Our country can’t afford this partisan dysfunction any longer.”
