A rule adopted Friday by the Democratic National Committee’s rules and bylaws panel would require that any person who runs for the party’s presidential nomination must fully commit to the Democratic Party.

Randi Weingarten, president of the American Federation of Teachers and a member of the DNC, said the party “changed the rules to ensure to run for President as a Democrat you need to be A Democrat,” in a tweet along with a photo of the rule’s language after it was included in the proposed draft call for the 2020 Democratic convention at a meeting in Providence, R.I., Yahoo News reported.
