@ehBeth,
That cap has to be for more than $2000 a year. Significantly more. This $2000 over many years.
Just did a quick search:
I can find no federal honorarium restrictions for elected officials (though there are some for Federal employees and officials).
There are state laws but they are liberal in what they allow for in the most part. Vermont, for example has no restrictions.
Here's a web site that deals with these regulations:

Honorarium Restrictions
Updated October 2015
The U.S. Office of Government Ethics defines "honorarium" as a payment of money or anything of value for a "series of appearances, speeches, or articles if the subject matter is directly related to the individual's official duties or the payment is made because of the individual's status with the Government." Most states characterize the issue is a similar way.
Twenty-eight states prohibit legislators from receiving an honorarium if it is given in connection to a legislator’s official duties as a public officer. Out of the 28 states that prohibit honorariums for official duties, 19 allow legislators to accept honorarium for services performed in relation to his or her private profession or occupation. Nineteen states that prohibit honorarium allow for reimbursement for travel, lodging and necessary expenses
Eleven states specifically allow honorariums in statute. Eleven other states do not address honorariums in statute, though a state’s conflict of interest law may apply. Colorado and Georgia are among the few states that allow honorariums up to a certain amount. States that allow honorarium typically stipulate that any payment received must not influence a legislator's official duties. At least 10 states that allow honorariums require that they be disclosed.
