It could also be seen as a bid by the former White House chief strategist to revive his own political fortunes.
Since May, Bannon has been paying his surrogates to produce political ads in cities across the United States, according to people with direct knowledge of the matter.
The campaign will tout the Trump administration's accomplishments that dovetail with Bannon's own America First views, including passing a comprehensive tax reform bill and working with Congress to curtail the Dodd-Frank Act's impact on community banks, people said.
The ads will argue that Trump needs Republicans to control the House and the Senate in order for him to continue to pursue his agenda, the people added. The ads will not endorse specific candidates but rather the need for Republicans to maintain control of both chambers.
