Greg Stanton’s office announced the launch of the bipartisan U.S.-Mexico Congressional Caucus and said it would strengthen the bilateral relationship and facilitate dialogue on trade, security, and cultural cooperation.

This is direct official evidence that Stanton helped launch the caucus, satisfying the launch portion of the claim.

The official launch notice names Joaquin Castro and Rudy Yakym as the caucus co-chairs, and lists Greg Stanton only as an inaugural member, not a leader of the caucus.

This shows Stanton participated in the caucus but was not identified as a co-chair or lead, so the full 'lead' portion of the claim is not yet proven.
