Meta Platforms will let political ads on Facebook and Instagram question the legitimacy of the 2020 U.S. presidential election, one of several changes the social-media company and other platforms have made to loosen constraints on campaign advertising for 2024.

Meta made the change last year, but it hasn’t gained wide attention. The company decided to allow political advertisers to say past elections were “rigged” or “stolen” but prevented them from questioning the legitimacy of ongoing and coming elections.
