Trump can't make recess appointments thanks to Alaska Republican he attacked

Amid concerns that President Donald Trump may try to fill positions while Congress in in recess for August, the Senate moved to ensure he's unable to do just that.

According to The Hill, Sen. Lisa Murkowski (R-AK) (who Trump attacked earlier this year) wrapped up the Senate's session by locking in nine "pro-forma" sessions -- incredibly brief sessions that sometimes only last a few minutes -- during their summer break.

In doing so, she ensured that "the Senate will be in session every three business days throughout the August recess," and has historically been used to block recess appointments in the past -- most recently when President Barack Obama attempted to fill former Justice Antontin Scalia's seat on the Supreme Court.

The move, which the Senate voted for unanimously, came amid tensions between Trump and Attorney General Jeff Sessions, who many in Washington fear will be fired in the coming weeks.
