This is a long-running conflict with Russia. There really are issues in the US that need to be fixed (as the Soviets gladly pointed out about Jim Crow in the 1950s/1960s), but Russia is also geopolitically smart enough to attack those vulnerabilities. If you just sit down and consider why and what advantages Russia would have in spreading propaganda, it is hard to believe they aren't doing it.
Dozens more resources that track, analyze and report on Russian trolling / propaganda. It's so easy to find, you must be trolling.
