In response to the letters of Sister Veronica Piccone, M.S.C., and Lucille Kennedy, regarding abortion and immigration (CNY, April 26), there is no issue more important than protecting the lives of the unborn, the most vulnerable of all. It is our foremost duty as Catholics, as Christians and as human beings. The Republican Party has done no harm to the poor and/or immigrants, and by that I mean legal immigrants who have followed the law and entered this country properly. Parents are responsible for their children, not the government, and as a sovereign nation, it is the duty of our government to protect U.S. citizens. Donald Trump is the most pro-life president since Ronald Reagan, and the most outspoken in protecting religious institutions.
