I serve as Chairman of Americans for Limited Government. I have been a leading force in the limited government movement since 1992, when I founded the group U.S. Term Limits. Fifteen states now have term limits on their legislatures. Since then the term limits movement has grown to one of the largest grassroots movements in American history.

I also serve on the board of various nonprofit organizations, including the Cato Institute, the Club for Growth and the Friedman Foundation for Educational Choice. 

In 2000, I founded Legislative Education Action Drive (LEAD) which focuses on enacting school choice legislation across the country. I also serve as Chairman of Parents in Charge Foundation.

I am a strong supporter of school choice and have been honored with the Herman W. Lay Memorial Award for my work in education.

I have made my living by investing in various properties. In 1970 I purchased my first multiple-dwelling in Manhattan. By 1986 I had accumulated seventeen buildings and did building-wide renovations in all of them. In 1986 I sold the entire portfolio with the exception of two parcels. After the stock market debacle in 1987 I sold my remaining property. I started buying Manhattan properties again in 1990.
