The "Outnumbered" panel sounded off after a former Democratic congressional intern was arrested for posting online the personal information of at least three Republican senators during last week's Senate Judiciary Committee hearing. 

Jackson Cosko, 27, is accused of doxxing Sens. Lindsey Graham of South Carolina, Mike Lee of Utah and Orrin Hatch of Utah on their respective Wikipedia pages.

Capitol Hill police on Wednesday were investigating additional doxxing incidents involving at least two more senators, including Rand Paul of Kentucky, but it is not clear if Cosko is connected.

Cosko was most recently working as an unpaid intern for Rep. Sheila Jackson Lee (D-Texas), senior congressional sources told Fox News. In the past, he has worked with other Democratic lawmakers, including Sen. Dianne Feinstein (Calif.), Sen. Maggie Hassan (N.H.), and former Democratic Sen. Barbara Boxer (Calif.).

Fox News contributor Lisa Boothe condemned Cosko's actions, and argued that this is part of a dangerous pattern of behavior from the left.

She noted that this doxxing comes just a little more than a year after a gunman opened fire on a Republican congressional baseball practice, nearly killing House Majority Whip Steve Scalise (R-La.), and just months after Rep. Maxine Waters (D-Calif.) urged people to confront and harass members of the Trump administration in public.

"Republicans need to confirm [Kavanaugh], not just because he deserves to be confirmed, but they need to stand up to the bullies on the left and the complicit media," Boothe said.

Democratic strategist Capri Cafaro acknowledged that she is "very disappointed" in her own party.

"We've gotten away from issues, we have sensationalized everything, we've gone further into a toxic environment," Cafaro said, recalling a famous line from Michelle Obama.

"'When they go low, we go high.' We've totally forgotten about that."
