John McCain, others witness immigrant climb border fence
One illegal immigrant may have the worst timing in history.
On Wednesday, Sen. John McCain was taking a tour of the U.S.-Mexico border near Nogales, Ariz. when something unusual happened.
A bollard fence is one that is not solid, but has small gaps in between steel posts.
McCain subsequently tweeted that the woman was apprehended by Border Patrol agents.
McCain was joined in the tour by Sen. Jeff Flake (R-AZ), Sen. Chuck Schumer (D-NY) and Sen. Michael Bennet (D-CO).
