By CHEYENNE HASLETT, ABC News (WASHINGTON) -- In the week since members of Congress were offered vaccines, moral schisms have emerged on Capitol Hill about whether politicians deserve the shots ahead of their own constituents, particularly doctors and nurses working on the front lines. On both sides of the aisle, some members have responded by declaring that they won't get the vaccine yet because they don't want to "cut the line." But their decisions defy national security concerns and public health recommendations, according to infectious disease experts across the country. The vaccine became available to Congress about a week before Christmas, after the National Security Council announced Congress would be allotted doses of the vaccine to protect "continuity of government operations."
