MEMORANDUM **

We have reviewed appellant’s response to this court’s April 10, 2007 order to show cause and conclude that the questions raised in this appeal are so insubstantial as not to require further argument. See United States v. Hooton, 698 F.2d 857, 858 (9th Cir. 1982) (per curiam) (stating standard). Accordingly, we summarily affirm the district court’s judgment.

AFFIRMED.
