National News Obama pitches immigration steps in his hometown November 25, 2014 23:49 GMT By JIM KUHNHENN Associated Press WASHINGTON (AP) -- President Barack Obama says the contributions that a broad patchwork of immigrants has made to the United States helps justify the executive actions he took to protect workers illegally in the country from deportation. Obama defended his immigration executive actions Tuesday, and called on Republicans to pass a comprehensive immigration system overhaul. The president spoke at a community center in a predominantly Polish-American neighborhood of Chicago. The White House is trying to broaden the appeal of the immigration measures beyond the predominantly Latino population it would help. Three hecklers interrupted Obama, saying he had not done enough to stop deportations. After listening to them, he said: "There are other ways of engaging. Just sit down."
