(Phoenix, AZ) -- Congresswoman Nancy Pelosi is coming to Phoenix tomorrow. Her visit is an effort to prime Arizona to be competitive for Democrats in November. She'll take part in a Facebook Live session tomorrow afternoon with U.S. Representative Raul Grajalva moderated by The Arizona Republic. Republican Representative Martha McSally is running for the U.S. Senate seat being vacated by Jeff Flake, creating a potential House vacancy Pelosi would love to see filled by an Arizona Democrat.
