The allegations: Arlene "A.J." Delgado claims in the suit, filed in federal court in Manhattan, she found herself "excluded from participating in the communications work of the inauguration or in any capacity," after she announced in December 2016 she was pregnant and that the father was Jason Miller, a married senior communications strategist.
