pendennis, you are splitting hairs, D.C. is a federal district and enforcement of laws take place by law enforcement who arrest violators in the federal district and REGARDLESS of the charge; the suspect is prosecuted by the U.S. Attorney's Office which is federal.
The U.S. Attorney's office prosecutes violations of both <i>local / non- federal </i> & <i>federal crimes</i>.
So regardless, this fellow is not charged with a FEDERAL charge per se, however, ANY AND ALL charges are prosecuted by the only prosecutor's office in the District of Columbia, which is the United States Attorney's office. Yes there are different divisions within the United States Attorney's office, but still, there is not a local, elected prosecutor. All divisions still answer to THE UNITES STATES ATTORNEY.
The U.S. Attorney is personally appointed by the President. The presidential appointed U.S. attorneys for the various districts in each state and U.S. possessions/territories answer directly to the United States Attorney General.
This is currently Eric Holder. Attorney General Holder answers directly to the President.
And by the way, if not obvious, U.S. Attorney's are federal employees as are the Presidential Appointed federal magistrate and federal judges. Get convicted in D.C. and after one finishes said jail/prison sentence, one will find themselves visiting another federal employee, i.e., a U.S. probation officer.
So still... Hopefully the jury sends a strong message to Obama's personally appointed U.S. Attorney that heads the U.S. Attorney's office for the District of Columbia which is responsible for the charges against this man.
