Washington, DC – Wyoming Senator Mike Enzi was among a group of congressmen who received flu shots two days after federal officials announced a shortage of the vaccine. Several lawmakers turned down a chance for a flu shot to avoid the appearance of preferential treatment. Enzi's spokesman says the Senate physician recommended the flu shot, as did Senate Majority Leader and doctor, Bill Frist. Senator Craig Thomas of Wyoming also received a flu shot, but his spokesman says Thomas got it several days before the shortage was announced. Representative Barbara Cubin did not receive a shot.
