Senior adviser rejects rumors of shake-up in Trump campaign leadership

Lewandowski, a controversial figure who was fired by Trump in 2016 after grabbing the arm of a reporter and four years later lost his position overseeing a pro-Trump political fund amid claims he made unwanted sexual advances on a Trump donor, was re-admitted to the campaign last month.

But rising speculation that Wiles and LaCivita might be pushed aside in favor of Lewandowski and former presidential counsellor Kellyanne Conway have not materialized into a campaign shake-up.

An ABC News/Ipsos poll released on Sunday showed Kamala Harris with a four-point lead over Trump among registered voters 50%-46%, and a six-point advantage among likely voters, 52%-46%.
