With just 46 days until voters take to the polls, second gentleman Doug Emhoff has been on the campaign trail supporting his wife, Vice President Kamala Harris, as she campaigns to be the next president.

The rally, scheduled Monday in San Antonio, will be joined by with the city's mayor, Ron Nirenberg, as well as former Mayor Julián Castro and his twin brother, U.S. Rep. Joaquin Castro. Tuesday's events will include stops in Austin and in Houston.
