The Biden campaign and the Trump PAC launch a duel of ads on immigration, a decisive issue in the election. The ads focus on an issue that is expected to be one of the most influential in voters' decisions in November.
About 28% of Americans named immigration as the most important issue facing the United States, according to a Gallup poll. In a split-screen moment last month, Biden and Trump visited the southern border and spoke at the same time in different locations. The announcements are not the first time the two candidates have faced off over immigration issues.
