America in Brief
U.S. signs deal with Denmark over Greenland, SCOTUS stalls Trump postal rule for mail-in ballots, and U.S. imposes new sanctions on Russia and Iran.

TL;DR
- The U.S. has reached a security agreement with Denmark regarding Greenland.
- The agreement gives the U.S. permanent control over Greenland's security.
- It prevents U.S. adversaries from having bases, military presence, or sensitive investments in Greenland without U.S. approval.
