President Trump rallies in Arizona

The theme of President Trump's Arizona campaign rally is immigration. His first stop in Arizona Tuesday was to inspect a U.S. Customs and Border Protection drone. His visit is also a chance to set the tone as legislators return from summer break. Building the wall along the U.S.-Mexico border was a core campaign promise. But the president may be willing to break another one to get it. Fox News reported the White House may offer permanent status for young people brought into the country illegally when they were children, the so-called DREAMers -- in exchange for funding to build the wall.
