Chief of Staff John Kelly signed a "Cabinet order" on Tuesday expanding the authority of troops at the border to include "a show or use of force (including lethal force, where necessary), crowd control, temporary detention, and cursory search" in order to protect border agents, according to the Military Times' Tara Copp.

Why it matters: Requests for troops to provide crowd and traffic control and protection for agents had previously been rejected by the Pentagon. Troop activities at the border have been largely restrained due to the Posse Comitatus Act of 1878, which prohibits the military from acting as law enforcement on U.S. soil. Defense officials told the Military Times that the language in the order "was carefully crafted to avoid running up against the bedrock legal limitations set in Posse Comitatus."

Why it matters: Apple is one of several Big Tech firms accused of violating the spirit, if not the letter, of antitrust law. A high-profile lawsuit could become a roadmap for either building a case against tech titans under existing antitrust laws or writing new ones better suited to the digital economy.

Younger Americans are increasingly concerned that Social Security won't be enough to wholly fall back on once they retire, according to a survey conducted by AARP — in honor of today's 85th anniversary of the program — given first to Axios.

Why it matters: Young people's concerns about financial insecurity once they're on a restricted income are rising — and that generation is worried the program, which currently pays out to 65 million beneficiaries, won't be enough to sustain them.

One in four Americans is worried their ballot won't be accurately counted this year, and four in 10 worry mail-in voting could yield less reliable results, according to a new Axios-SurveyMonkey poll.

The big picture: Partisan identification is a massive driver of distrust in both categories — and the stakes are huge this year.
