MUNICH — As America prepares for the 2020 presidential election, Microsoft President and Chief Legal Officer Brad Smith said tech companies have a 'fundamental responsibility' to safeguard America's democratic process.

"We have a fundamental responsibility as companies and as a technology sector to help protect our candidates from attacks and hacking. To help protect the integrity of voting, from voting polls to voting results and certainly the voting process itself," Smith explained at the annual Munich Security Conference.

"We have a fundamental responsibility not just to address but to fight disinformation and I think we have a fundamental responsibility to ensure that our business models do not sap the strength of democracy itself by creating polarized communities that eat away at the core of what makes every democracy successful," he added.

Smith's comments Saturday at the security forum followed those of Facebook CEO Mark Zuckerberg, who said that social media companies need more guidance and regulation from governments in order to tackle the growing problem of harmful online content.

"Even if I'm not going to agree with every regulation in the near term, I do think it's going to be the thing that helps create trust and better governance of the internet and will benefit everyone, including us over the long term," Zuckerberg told an audience Saturday at the Munich Security Conference.

"In the absence of that kind of regulation, we will continue doing our best, we are going to build up the muscle to do it, to basically find stuff as proactively as possible," he said, adding that he did not want Facebook to contribute to polarization or misinformation.
