Sen. Susan Collins, R-Maine, was heckled and drowned out at times by demonstrators at a ribbon-cutting ceremony in her home state Tuesday, the latest in a series of confrontations between protesters and members of Congress.

“Shame! Shame! Shame!” protesters yelled at Collins as she cut the ribbon to mark the completion of the long-running Route 1 construction project in Searsport.

The demonstrators were yelling about cuts to Medicare, Israeli attacks on Gaza and Donald Trump’s nominees on the Supreme Court, video of the event shows.
