In a significant political move, House GOP Policy Committee Chairman Kevin Hern has formally announced his campaign for the U.S. Senate seat that is likely to be vacated by current Senator Markwayne Mullin, R-Okla. This departure comes as Mullin has been selected to lead the Department of Homeland Security (DHS) under President Trump. Hern, a notable figure in House GOP leadership, is rallying support and framing his campaign around key Republican issues, emphasizing loyalty to the Trump agenda and opposition to what he characterizes as threats posed by the radical left and moderate Republicans, whom he refers to as 'RINOs' (Republicans In Name Only).
