Lawrence Jones took a page from Michelle Obama's book and commented that some Democrats are "going low again" with their comments inciting violence.
Rep. Maxine Waters (D-CA) said she felt inspired to "take out Trump" in a speech in New York earlier this month.
"When you incite violence, that should be investigated," Jones told "Fox & Friends" on Monday.
"I'm not so concerned about Maxine Waters. I'm concerned about the people that listen to her, the people that tried to assassinate Republican congressmen at a baseball field," he said.
Waters' comment comes only months after a Bernie Sanders supporter opened fire on a congressional Republicans' baseball game in June, wounding Rep. Steve Scalise (R-LA).
"These same congresspeople, especially Maxine Waters, promised after the Steve Scalise shooting that they would tone down the rhetoric," Jones said.
