The e-mail included a mock version of a Congressional bill, H.R. 4667, which was rife with errors. The text included a chart outlining how the rates would supposedly increase "to bring monies in line to the America[sic] middle class." Here is a copy of the phony bill:

Recently, Congress did pass a version of H.R. 4667 that will increase COLA rates for 2011 keeping with the standard percentage increases in Social Security taking effect on Dec. 1, 2010. To view a copy of the bill, which is now Public Law 111-247, Click Here.
The hoax bill was forwarded to AMVETS National Headquarters by an AMVETS National Service Officer in Georgia who was suspicious of the e-mail's content, after receiving it from a client. Other service officers soon started to receive similar inquiries into the validity of the e-mail.
AMVETS National Legislative Director Ray Kelley quickly discovered that the e-mail was fake and AMVETS National Service Department informed service officers in the field, providing each of them with the accurate bill to properly inform the veterans they serve.
Stars & Stripes Rumor Doctor also caught wind of the e-mail and published findings on the hoax.
AMVETS leaders supported the real version of H.R. 4667, which ensures veterans' service-connected compensation will increase for 2011, accounting for perpetual increases in the cost of living.
