Klobuchar, D-Minn., recently introduced legislation that would aim to limit Section 230, the liability shield for social media platforms, as debate increases around misinformation for both elections and health issues.
"Senator Warner and Hirono and I already introduced a bill that would focus on discriminatory content and the like when we have a public health crisis and people are dying every day," Klobuchar said on CNN’s "State of the Union."
"These are the richest companies in the world," she continued. "There is absolutely no reason they shouldn't be able to monitor this better and take this crap off of their platforms that are basically telling people, 'Oh, hey, there's problems,' when we know science proves there isn't."
Klobuchar’s Safe Tech Act, introduced in February, aimed to hold companies like Google, Twitter and Facebook accountable for content related to harassment, but Klobuchar wants to see legislation tackle the disinformation around vaccinations more specifically.
Her comments reinforce the stance among Democrats after President Biden said Facebook was "killing people" by not acting to more stringently monitor "COVID misinformation."
"They’re killing people," Biden responded. "The only pandemic we have is among the unvaccinated, and they’re killing people."
White House press secretary Jen Psaki said the administration was communicating with Facebook to work on limiting "misinformation" on the platform.
Klobuchar said social media "greatly" contributed to "misinformation," citing numbers that "two-thirds of the people who have not got vaccinated say … they’ve got something off of social media."
Her solution: break the companies up to dilute their reach and influence.
"Part of this is they gobbled up so many companies that you don't even have the chance that other media platforms could do this on social media," Klobuchar said. "So I am a fan of using antitrust to look back and see if they should divest assets so we can get true competition again."
