Faith groups are ramping up pressure on Congress to pass immigration reform. In early September, Catholic priests and bishops around the country will deliver sermons on immigration, part of a larger effort to persuade Catholic lawmakers to support an immigration bill. Meanwhile, some Christian activists in California are marching for 21 days on what they call a pilgrimage for citizenship. A group of prominent evangelical Protestants is now running radio ads aimed at 50 mainly conservative House members who rejected an immigration bill approved by the Senate.
