House Chief of Staff. In 2021, after Trump lost re-election, the Heritage Foundation hired Chad Wolf, Ken Cuccinelli and Mark Morgan, all three of whom played a prominent role in the immigration policies of the Trump administration. It also hired former Vice President Mike Pence. Shortly thereafter, Pence published an op-ed on a Heritage Foundation website which made false claims of fraud in the 2020 election, as well as numerous false claims about For the People Act, a Democratic bill to expand voting rights. Biden administration In 2021, the Heritage Foundation shifted from its traditional style of conservatism to firebrand, Trump-style conservatism. Right-wing figures and Trump allies frequently criticized Heritage Foundation positions under the leadership of Kay Coles James in 2020 and 2021, prompting her to step down in March. She was replaced by Kevin Roberts, the head of the Texas Public Policy Foundation and member of Texas Governor Greg Abbott's COVID-19 task force. Activities The Heritage Foundation has been considered one of the world's most influential think tanks. The 2020 Global Go To Think Tank Index Report ranks Heritage as sixth among the "top ten think tanks in the United States" and thirteenth worldwide. Heritage published a 1981 book of policy analyses, Mandate for Leadership, that offered specific recommendations on policy, budget, and administrative action for all Cabinet departments. The Heritage Foundation also publishes The Insider, a quarterly magazine about public policy. Until 2001, the Heritage Foundation published Policy Review, a public policy journal; the journal was then acquired by the Hoover Institution. From 1995 to 2005, the Heritage Foundation ran Townhall.com, a conservative website that was subsequently acquired by Camarillo, California-based Salem Communications. Under Jim DeMint's leadership, the process involved in publishing policy papers changed at the Heritage Foundation. Whereas previous senior staff reviewed policy papers by authors, DeMint and his team heavily edited policy papers or shelved them. In response to this, several scholars at the foundation quit. Internationally, Heritage publishes the annual Index of Economic Freedom, which measures a country's freedom in terms of property rights and freedom from government regulation. The factors used to calculate the Index score are corruption in government, barriers to international trade, income tax and corporate tax rates, government expenditures, rule of law and the ability to enforce contracts, regulatory burdens, banking restrictions, labor regulations, and black market activities.
