Just another day in the life Malia Obama lol. A marriage proposal from sone crazy guy...no big deal! The Secret Service took him into custody tho because apparently, he's got a sketchy past with the White House.

Who is he you ask? His name is Jair Nilton Cardoso. He is 30-years old. This guy showed up at the Weinstein Company offices in Manhattan where Malia is interning. TMZ was told the man held a sign up against an office window that read, "Will you marry me?".

Agents kicked him out, but 2 days later he showed up again outside another building where Malia was working. This time agents recognized him as a guy who'd attempted to get into the White House multiple times.

TMZ was told Malia never felt threatened because her agents were there and, as one person put it ... "she didn't want to make a stink" about the situation. Agents interviewed Cardoso, determined he needed psychiatric evaluation and took him to a hospital.

He was not charged with a crime.

Thank God for the Secret Service!
