A left-wing political operative attempted to blame the attempted assassination of a Democratic candidate for mayor in Louisville, Kentucky on conservatives in a Tuesday tweet.

Cliff Schechter, a former ad writer for then-candidate Joe Biden’s presidential campaign, blamed “conspiratorial right-wing rhetoric” for the assassination attempt on Democratic mayoral candidate Craig Greenberg.

The alleged suspect, Quintez Brown, is an anti-capitalist activist who praised Che Guevara and Mao Tse-Tung in a post on Twitter.
