House Foreign Affairs Committee Chair Michael McCaul, who was criticized last spring when he said Russian propaganda had targeted much of his party's base, indicated Sunday that reports from the Biden administration concerning a Russian scheme to influence the upcoming election reflect what's been happening for years.

"The Russians have been trying to do this for many years," the Texas Republican told CBS News' "Face the Nation." "So has China and so has Iran, for that matter, and it's intensified."

Last week, the Biden administration unsealed criminal charges against employees of a Russian state-run media company, while seizing internet domains that the Kremlin has been using to spread disinformation.
