NEW YORK (AP) — Roman Catholic groups on Thursday embarked on a two-week campaign of prayer vigils, rallies and other events to draw attention to what they consider government attacks on religious freedom.

Called the “Fortnight for Freedom,” bishops organized the education campaign during liturgical feasts for martyred defenders of the faith. Independent advocacy groups such as CatholicVote.org and Women Speak For Themselves, have joined the effort with TV ads, videos, Facebook appeals and petition drives.
