Rep. Phil Roe (R-Tenn.) announced Friday he won't seek re-election in 2020, per WCYB.

The big picture: Roe, the ranking member of the House Veterans' Affairs Committee, is the 25th Republican to announce he will not run for re-election this cycle.

  • Roe told the Johnson City Press last month that he would base the decision to run for a seventh term on "personal" reasons and not political factors like President Trump's impeachment.

Of note: President Trump won Roe's district in 2016 by a nearly 57-point margin.

  • Roe's congressional seat has been held by a Republican since 1881.

What he's saying:

“The challenges we are facing now as complex as ever, and I still have a lot of fire in my belly. I look forward to finishing my term strongly for the East Tennesseans that I love representing and working with President Trump in favor of the free-market, conservative policies so many of us hold dear. I am equally confident East Tennessee is full of capable public servants who will step up to fill my void, and I am ready to give them the opportunity to do so."

This is one of the bigger signs of trouble for President Trump that we've seen in a poll: Of the final debate's seven topics, Joe Biden won or tied on all seven when viewers in a massive Axios-SurveyMonkey sample were asked who they trusted more to handle the issue.

Why it matters: In a time of unprecedented colliding crises for the nation, the polling considered Biden to be vastly more competent.

The murder hornets are here

Entomologists in Washington state on Thursday discovered the first Asian giant hornet nest in the U.S.

Why it matters: You may know this insect species by its nom de guerre: "the murder hornet." While the threat they pose to humans has been overstated, the invading hornets could decimate local honeybee populations if they establish themselves.
