Left-wing activists following and filming Sen. Kyrsten Sinema, D-Ariz., in a bathroom attracted plenty of criticism this week, but one co-host of "The View" warned of possible bloodshed if such tactics continued.

During a discussion of Sinema and Sen. Joe Manchin, D-W. Va., who have held up a $3.5-trillion Biden administration spending package over price concerns, Sara Haines objected to public confrontation tactics to change their minds.

The antics came to a head Sunday when activists stalked Sinema into a bathroom at Arizona State University, where she teaches in addition to her Senate duties. 

"I don't think the way this was handled, following someone into a bathroom is [never] a good idea," Haines said. "In this day and age where we live in a very big gun country … Over 300 million guns across this country. When you confront people, it may not end well. It's not going to effectuate change most likely when you're harassing people."

The show's liberal hosts have repeatedly expressed frustration with Sinema and Manchin for not getting onboard with Biden, with Behar calling them "enemies" of democracy last week.

CNN'S ANA NAVARRO SUGGESTS KYRSTEN SINEMA DESERVED BEING HARASSED IN BATHROOM

Co-host Sunny Hostin agreed that the bathroom incident was wrong but fumed at Sinema for not being more responsive.

"We shouldn't be following a Senator into the bathroom. They should have just waited for her to come out," she said. "Talk to her then … But she never answers questions … She doesn't answer questions outside of the bathroom. She doesn't answer questions inside of the bathroom. She doesn't answer questions on the plane."
