Lawyers for an Idaho man who has pleaded guilty to firing an assault rifle at the White House in 2011 don't want a "terrorism enhancement" to apply to his case.

Oscar Ramiro Ortega-Hernandez' lawyers wrote in court filings Monday that the application of a "terrorism enhancement" is unconstitutional, though he accepted it as part of his guilty plea in September. An enhancement increases the penalty for a charge in terrorism cases

Lawyers also asked that Ortega-Hernandez be allowed to speak with the judge privately.

Federal sentencing guidelines recommend Ortega-Hernandez spend 24 to 27 ½ years behind bars. But his lawyers compared his case to that of Joseph Reel, recently sentenced to nearly three years for rigging his Jeep to crash into a White House Secret Service guard booth.

Ortega-Hernandez is scheduled to be sentenced March 19.
