Share Source: Al Drago/Pool via AP Texas Sen. Ted Cruz (R) on Sunday penned a letter to Defense Secretary Lloyd Austin over the Military's use of official Armed Forces' communication channels to address Fox News host Tucker Carlson's criticisms. The senator pointed out that Military members are prohibited from using their official capacities to engage in partisan politics. Instead of abiding by the Department of Defense's policies, Pentagon officials, Cruz said, used public attacks on Carlson "for the sake of leftwing ideology and political expediency." One of the primary concerns the senator has is with Military officials saying civilians are not allowed to criticize the Armed Forces unless they themselves have served. Engaging in this kind of behavior, Cruz said, "weaponizes" the Military and breaks generations of tradition.
