Biden outlines immigration policies, including citizenship for DREAMers

Former Vice President Joe Biden touted his "sensible" immigration proposals and hit President Trump for a re-election strategy he called "morally bankrupt" in an op-ed published Monday.

In the Miami Herald, Biden called on Congress to "make it official" that "DREAMers are Americans," also saying undocumented immigrants in the United States must be "brought out of the shadows through fair treatment, not ugly threats." The U.S asylum system needs to be improved in ways that will "streamline and strengthen it," Biden wrote.

Biden went on to say that it's "imperative" to secure the border by "improving screening procedures at our legal ports of entry and making smart investments in border technology," but not through building a wall, which Biden referred to as a "slogan divorced from reality."

The Democratic presidential frontrunner went after Trump in the op-ed for policies he says are intended to "assault the dignity of the Latin community and scare voters to turn out on Election Day," also saying that the president "invokes racist invective to describe anyone south of the Rio Grande" while describing "horrifying scenes at the border of kids being kept in cages" that "subvert American values and erode our ability to lead on the global stage."

Biden published his op-ed three days before he'll head to Miami for the first Democratic presidential debate; he's set to take the stage on the second night, June 27.
