So, secret service didn’t take him in for “emergency evaluation.”
I don’t know who/what agency exactly you could contact, but perhaps start wtih the Department of Mental Health in DC, whose 24/7 help line is 1(888)7WE-HELP or 1-888-793-4357 http://dbh.dc.gov/service/access-helpline. There is a mobile crisis line there too: “Mobile crisis services is available from 9 am to 1 am every day and can be activated by calling (202) 673-9300.”
Did you file a petition in DC?
If you filed a petition in a different county or state, there might be different laws or a better judge in DC that allows hospitalization. District of Columbia - Treatment Advocacy Center According to this link, “D.C. case law has interpreted “injury” to mean the likelihood of an individual inadvertently placing himself or herself in danger or likelihood of suffering harm. An overt act of physical danger or violence is not required.”
The officers in DC could not use the information that his doctors said he needs long term commitment. Officers did not use the information that he has a diagnosis of (?) and is unmedicated, delusional, paranoid, has not slept or eaten in four days, tried to contact the White House, and you fear he will do something drastic or put himself in harm’s way with his need to contact the White House. Also, he does not plan on coming home until he can find someone to believe him. All of that information can go onto a petition.
DC law allowing you to file petition for outpatient commitment:
"For inpatient or outpatient commitment: Proceedings for the judicial commitment of a person in the District of Columbia may be commenced by the filing of a petition with the Commission by his spouse, parent, or legal guardian, by a physician or a qualified psychologist, by a duly accredited officer or agent of the Department, by the Director of the Department or the Director’s designee, or by an officer authorized to make arrests in the District of Columbia.
“For emergency evaluation: An accredited officer or agent of the Department of Mental Health of the District of Columbia, or an officer authorized to make arrests in the District of Columbia, or a physician or qualified psychologist of the person in question, who has reason to believe that a person is mentally ill and, because of the illness, is likely to injure himself or others if he is not immediately detained may, without a warrant, take the person into custody.”

Good luck. My family member became extremely ill and is currently incarcerated because the moment the standards for involuntary hospitalization were met, a law was broken. Our system further harms people with serious mental illness, but we still have to try for the best outcomes.
I want a good outcome for your son.
