The Republican National Convention has at times lacked something that every political convention needs, a former aide to President Ronald Reagan said Wednesday.
That thing is positive energy.
"This is my 10th convention, and conventions are about positive energy. It's a little lumpy right now," BGR Group co-founder and Republican lobbyist Ed Rogers told "Squawk Alley" on the sidelines of the RNC in Cleveland.
"There's a lot of other images, messages, words, phrases coming out of this convention that aren't all about positive energy," he said, responding to a question about comments from Republicans at the convention.
Would-be GOP presidential nominee Ben Carson on Tuesday suggested that presumptive Democratic presidential nominee Hillary Clinton's role model is Satan.
Also on Tuesday, New Jersey Gov. and former Trump rival Chris Christie led the crowd in chants of "Lock her up" and "Guilty" directed at Clinton, who was investigated by the FBI over her use of a private email server while secretary of state.
The State Department reopened its investigation into the issue after the FBI recommended that no criminal charges be brought against Clinton or anyone in her inner circle.
