Rep. Mike Gallagher (R-Wis.) and the "Outnumbered" co-hosts on Monday weighed in on the social media spat between Donald Trump Jr. and congresswoman-elect Alexandria Ocasio-Cortez.

It started on Thursday when Trump Jr. took to Instagram to share a meme mocking Ocasio-Cortez's (D-N.Y.) democratic socialist policies.

The incoming lawmaker fired back on Twitter, claiming that he makes comments about her when there are developments in Special Counsel Robert Mueller’s Russia investigation. She also mentioned that she will be part of a body that has subpoena power.

Ocasio-Cortez later clarified that it was not a "threat," as she will not have the power personally to subpoena anyone.

Gallagher offered his main takeaway from the social media dust-up: "Social media is making us all stupid."

"We should unplug, turn off our phones, delete Twitter and spend less time on it," Gallagher said. "And have actual face-to-face conversations with people. And don't just surround yourself with people that agree with you, but seek out people that disagree and have a civil conversation."

Jessica Tarlov said it's not smart to throw around terms like "subpoena," especially since Ocasio-Cortez hasn't even taken her seat yet.

She said it is a good thing, however, that Ocasio-Cortez is savvy on social media, which Tarlov said the incoming lawmaker uses to bring greater transparency to Congress and involve her constituents.

Kennedy said she appreciates that Ocasio-Cortez is so active on social media, because she consistently highlights just how "empty-headed" her ideas are.

She said that going after President Trump or his family on Twitter comes across as very "inauthentic."

"She needs to revert back to what it was about her that resonated with voters that allowed her to unseat a popular, long-term incumbent," Kennedy said. "I think she's gotten away from that, and she's bought into her own mystique, which is certainly tarnished a bit in the last few interviews."
