Facebook and Twitter are working to remove millions fake accounts targeting U.S. veterans.

Groups of U.S. veterans testified before Congress on Wednesday.

They say foreign accounts are increasingly targeting older veterans with online misinformation campaigns.

The foreign campaigns included creating fake veterans’ support pages.

In some cases, they convinced veterans to send campaign donations overseas.

In others, they spread divisive political content sometimes related to the 2020 presidential race.

Both Facebook and Twitter said they’re making strides in fighting fake content.
