This morning on Fox and Friends William LaJeunesse reported on what constitutes an "assault weapon" as far as the federal government is concerned.

President Obama will announce his proposals for tighter restrictions on guns later today. He is expected to push for the re-implementation of the assault weapons ban, which was in effect for a decade until 2004.

LaJeunesse says some people argue the term "assault weapon" is misleading. He went to a Phoenix gun shop to find out more on assault weapons, including some common myths about the firearms.
