Asked and answered. Ted Nugent is one guy who apologized.

Whereas all these Dems holding up Trump's bloody severed head or otherwise killing him in effigy, NONE of these Dems are apologizing. The greater uncivility, the disturbing threats to attack or kill Trump or other Republicans, actually doing it (Rep. Scalese at the baseball park, etc.), and just attacking any Republican speaking publicly (Antifa, students at bookstores and universities attacking Karl Rove, Ann Coulter, Yiannopoulos, even Condolleezza Rice, not even letting them speak) manifests vastly greater propensity for uncivility and actual violence on the Democrat/Left.
