Dear @SecPompeo: You served on active duty. As a nation mourns McCain, it would be appropriate to lower the flag to half staff at all @StateDept buildings. I respectfully request you give that order, regardless of the views of @realDonaldTrump. It is the honorable thing to do. https://t.co/yIllKANhMq— Ted Lieu (@tedlieu) August 27, 2018
