Matthew Thomas Shea (born April 18, 1974) is an American politician and attorney. A Republican, he represents the 4th Legislative District in the Washington House of Representatives. In October 2018, Shea acknowledged that he had distributed a four page manifesto which called for the killing of non-Christian males if a war were to occur and they do not agree to follow fundamentalist biblical law. Shea was referred to the Federal Bureau of Investigation for investigation as a result. In April 2019, Shea was removed as State House Republican Caucus Chair for advocating violence against religious minorities and offering state surveillance of political enemies to members of hate groups.An investigative report commissioned by the House, issued on December 1, 2019, found that Shea "participated in an act of domestic terrorism against the United States", organized and supported "three armed conflicts of political violence", and advocated replacing the government with a theocracy and "the killing of all males who do not agree." A former ally of Shea provided documents showing that Shea and his supporters were planning to seize control of the region after the outbreak of civil war, installing Shea as governmental leader in order to institute "constitutional changes" to "sanctify to Jesus Christ". Immediately after the report was issued, Shea was removed from the House Republican Caucus, though he refused to resign.
