The Defense Department's inspector general plans to review how U.S. soldiers are actually used to support security operations at the U.S-Mexico border, according to a memo first reported by NBC News.

Why it matters: The review could answer some questions posed by House Democrats, who are concerned that soldiers deployed to the border could violate laws prohibiting the use of the military in civilian law enforcement.

What the IG plans to review, per the memo:

  • The amount of money used to support U.S. military deployment to the border and whether those funds are in compliance with federal law.
  • Military training for contact with civilians at the border and other training given to U.S. soldiers.
  • How military personnel coordinate with Homeland Security at the border.

Background: Roughly 5,000 U.S. troops were stationed at the border as of last month, per the Military Times.

The Big Ten announced Tuesday that it has voted to postpone its 2020 fall sports season, including football, due to risks posed by the coronavirus pandemic, hoping instead to play in the spring.

Why it matters: The move from one of the most prominent conferences in college sports will almost certainly prompt other Power Five leagues to follow suit.

In a show of unity at the Democratic National Convention, 13 of Joe Biden's former 2020 challengers will appear via video to talk about the party's vision for the country and how they'll work with Biden to get it done.

Why it matters: Coalescing around Biden and his eventual running mate will help Democrats head into the general election against President Trump with a united front — unlike what they did in 2016.
