There are no billionaires in Congress....lots of millionaires. There are two Dem Governors who are billionaires and of course President Trump is a billionaire.
Are you talking about Trumps cabinet? There are only two billionaires there as well.
Vice President...Pence ($800,000) Secretaries of Agriculture, Perdue ($6M) Commerce, Ross ($2.5B) Defense, Mattis ($5M) Education, Devos ($1.25B) Energy, Perry ($2M) Health and Human Services, Price ($10M) Homeland Security, Kelly ($4M) Housing and Urban Development= Carson ($30M) Interior, Zinke ($800,00) Labor, Puzder ($45M) State, Pompeo ($345M) Transportation, Chao ($24M) Treasury Mnuchin ($300M) Veterans Affairs Wilkie (under M) Attorney General..Sessions ($6M)
Probably more....Congress has steadily gotten richer over the years.
Obama only had one billionaire in his cabinet and the Dem Governors are new. So +1 in Cabinet +1 Potus +2 Dem Governors ------- +4 Billionaires currently
