In April 2019, after the House passed the resolution withdrawing American support for the Saudi-led coalition in Yemen, Lee was one of nine lawmakers to sign a letter to Trump requesting a meeting with him and urging him to sign "Senate Joint Resolution 7, which invokes the War Powers Act of 1973 to end unauthorized US military participation in the Saudi-led coalition's armed conflict against Yemen's Houthi forces, initiated in 2015 by the Obama administration." They asserted the "Saudi-led coalition's imposition of an air-land-and-sea blockade as part of its war against Yemen’s Houthis has continued to prevent the unimpeded distribution of these vital commodities, contributing to the suffering and death of vast numbers of civilians throughout the country" and that Trump's approval of the resolution would send a "powerful signal to the Saudi-led coalition to bring the four-year-old war to a close".
