Donald Trump Jr. dismissed reports on Monday that he and his siblings ousted their father’s campaign manager, Corey Lewandowski, due to concerns about infighting and disagreements with his approach.

“We released Corey Lewandowski from the campaign, but we had a great relationship. Everything was amicable,” Trump’s eldest son told MSNBC. “I think it’s just a very natural process of transition from campaign to presumptive nominee to actual nominee.”
