Defending Democracy Together is a right-leaning 501(c)(4) advocacy and incubation group founded in Washington, D.C. in January 2018. Its leadership consists of former Weekly Standard editor-at-large William “Bill” Kristol, Ethics and Public Policy Center senior fellow Mona Charen, and other conservatives. The group has taken positions in opposition to a number of initiatives by President Donald Trump, often through its project, Republicans for the Rule of Law; most prominently, it has supported continuing birthright citizenship and strongly supported the Justice Department investigation of Russian interference in the 2016 Presidential election. The group hosts a number of fiscal projects on issues such as immigration, trade, and U.S. foreign policy.
In October 2018, DDT co-signed comments submitted to the National Parks Service concerning a proposed rule change which would eliminate demonstrations on the White House’s southern sidewalk, require permits for demonstrations, and charge fees for “costs associated with permitted demonstrations.” The comments were also co-signed by left-of-center organizations, including the Arkay Foundation, Democracy Fund, Pritzker Innovation Fund, and Third Way. Ostensibly right-leaning co-signers included former Rep. Bob Inglis, the advocacy group Stand Up Republic, Hoover Institution senior fellow Larry Diamond, and the environmentalist Niskanen Center.
Defending Democracy Together was officially formed on January 3, 2018, according to filings with the Virginia State Corporation Commission. DDT lists its address as 1090 Vermont Ave. NW, Suite 800, in Washington, D.C.; the address is shared by Berman and Company, a political consulting firm catering to center-right clients.  According to the left-leaning Center for Responsive Politics, Berman and Company was connected with the Enterprise Freedom Action Committee, a PAC that spent $750,636 in advertisements against 2016 presidential nominee Donald J. Trump.   According to filings with the FEC, the Enterprise Freedom Action Committee also shared office space with Berman and Company. 
Defending Democracy Together manages the Becoming American Initiative, a fiscal project of the group created to “provide the conservative case for immigration and DACA reform.” The Initiative is headed by Linda Chavez, a DDT board member and former Reagan administration official.
Republicans for the Rule of Law
In February 2019, DDT launched a television advertisement in the Washington, D.C. area urging viewers to ask their congressional representatives to “terminate President Trump’s emergency declaration” at the U.S.-Mexico border. 
Defending Democracy Together has been criticized for taking at least $600,000 in two grants from Democracy Fund Voice, a 501(c)(4) group created and funded by left-wing mega-donor Pierre Omidyar. According to Democracy Fund Voice’s website, in May 2018 it “approved two grants to Defending Democracy Together: first in the amount of up to $100,000 over one year and then in the amount of up to $500,000 over one year” (image available here). 
Sarah Longwell is executive director of Defending Democracy Together. Longwell is a senior vice president for Berman and Company, the right-leaning political consultancy that shares office space with DDT.  In February 2019, Longwell wrote an op-ed in the Washington Post in her capacity as DDT executive director in which she wrote: “It was a failure of political imagination that helped put Trump in the Oval Office. A primary challenger may need only a little political imagination to begin the process of evicting him.” 
Charles “Charlie” Sykes is president of DDT and a senior fellow at the right-leaning Wisconsin Policy Research Institute. Sykes, a self-described “prominent and outspoken critic of Donald Trump,” is also a national advisory board member for the left-wing funding group Democracy Fund; Democracy Fund Voice, a “sister” nonprofit to Democracy Fund, has donated at least $600,000 to DDT. Sykes is also a board member for Stand Up Republic, a left-leaning organization funded by Democracy Fund Voice.   
Board of Directors
While public filings have not been released detailing DDT’s board of directors as of early 2019, the Defending Democracy Together Institute’s board of directors consists of Bill Kristol, Charlie Sykes, and executive director Sarah Longwell. 
Sarah Longwell is DDT’s executive director and a senior vice president for Berman and Company, the right-leaning political consultancy that shares office space with DDT. Another DDT director, Jordan Bruneau, is a former staffer for Berman and Company. 
DDT’s website also lists former U.S. Rep. Bob Inglis as a director. Inglis also serves as executive director of RepublicEn, a global warming advocacy and research group funded by left-wing environmentalist groups.
