Melania Trump is hosting executives from major online and social media companies to discuss cyberbullying and internet safety, more than a year after saying that would be her issue as first lady.
The meeting Tuesday marks her first public event on the topic, a choice some observers have questioned given that her husband often berates people on Twitter.
Amazon, Snap, Facebook, Google and Twitter are among the companies that are expected to attend the meeting. The Internet Association said it will also be represented.
All the major technology companies have strict policies prohibiting harassment and other bullying behavior on their services, but primarily rely on users to report abuses and weed them out.
They try to clearly spell out the kinds of remarks and other posts that won't be tolerated in special sections such as one Facebook, the largest online social network, has set up.
Instagram, a popular service among kids and young adults for sharing photos and videos, provides links to the U.S. government's anti-bullying site and tips from a cyberbullying research center on one of its help pages.
