Why it matters: This rally is three days after President Trump, Bannon’s former boss, was in Alabama rallying for Moore’s opponent — Mitch McConnell’s favored candidate Luther Strange. For Bannon to make a rare public appearance in such close proximity to Trump shows how invested he is in this race specifically, and attacking McConnell more generally. Another former White House adviser, Sebastian Gorka, rallied with Sarah Palin for Moore on Thursday.

From a source close to Bannon: “Steve is coming to Alabama to support President Trump against the Washington establishment and Mitch McConnell. Steve views Judge Moore as a fierce advocate of Trump and the values he campaigned on.”
