TikTok puts vulnerable Democratic senators on the clock

TikTok is launching a campaign to target senators facing tough election challenges to try and save the popular app from a House bill threatening its future in the United States.

The $2.1 million ad buy will run in Nevada, Montana, Wisconsin, Pennsylvania, and Ohio. Democrats fighting to hold on to seats in those battleground states are under mountains of pressure as Republicans believe they are on a glide path to retaking the upper chamber.
