Could some Comcast subscribers in Massachusetts soon be forced to tune into a Rhode Island TV station for ABC programming?

Four members of the state’s federal delegation are worried it could happen.

Sens. Ed Markey and Elizabeth Warren and Reps. Bill Keating and Joe Kennedy III expressed concern Thursday that subscribers to Comcast’s Xfinity TV service in Bristol County could lose access to WCVB, amid news that the cable company and the Boston-based ABC affiliate’s owner, Hearst, have yet to reach a new agreement.

“Particularly during the ongoing COVID-19 pandemic, loss of access to this station would be harmful to Bristol County viewers who rely on state-specific announcements to stay healthy and safe,” the four Massachusetts Democrats wrote in a letter to the leaders of Comcast and Hearst.
