As of my last knowledge update in October 2023, Donald Trump had faced legal challenges and criminal charges in several court cases, but the specifics you've mentioned about deploying Marines in A.L. (which presumably refers to a location like Alabama) are not clear. Political and military actions taken by a sitting president or former president can be complex issues involving national security, executive authority, and legal implications.
If there are specific allegations or events you're referring to, please provide more details for a clearer perspective. Legal actions involving public figures, especially former presidents, can be very nuanced and often involve legal interpretation, political ramifications, and public opinion.
