Critics of the Carlyle Group frequently note its connections to various political figures. Some of the sectors and companies it invests in are highly sensitive to political activity, indeed its actions may be viewed as a form of political arbitrage. This may create conflicts of interest when political decision makers have their own personal wealth linked to such investments. Unlike most private equity firms which are predominantly located in New York, Boston or around San Francisco, Carlyle is the only large private equity firm located in Washington, DC. Corporate headquarters are on Pennsylvania Avenue, midway between the White House and the Capitol building.
Critics will often refer to Carlyle as a private defense contractor, but this is not completely accurate. It is a private equity firm that owns controlling or partial interests in a portfolio of companies, some of which are contractors for the military (though this is the area for which it is most well known). For example, it lobbied for the XM2001 Crusader artillery project, because one of its portfolio companies would be able to share in the contract. Likewise, it has a history of leveraged buyouts in the aerospace and defense industries.
In the book House of Bush, House of Saud, author Craig Unger states that Saudi Arabian interests have given 1.4 billion Dollars to firms connected to the Bush family. That figure was quoted by Michael Moore in his film Fahrenheit 9/11. Nearly 90% of the 1.4 billion, about 1.18 billion, refers to Saudi Arabian government contracts awarded to defense contractor BDM in the early to mid 1990s. At that time BDM was owned by the Carlyle Group.
