President Donald Trump has been privately talking about withdrawing from the postwar defense treaty with Japan, according to three sources familiar with the matter.

Trump is telling confidants the treaty is unfair to the U.S. because it promises to help if Japan was ever attacked, but doesn't require Japan to come to America's defense, the sources told Bloomberg.

So far, the president hasn't taken any step toward pulling out of the treaty, which was signed in 1951, and administration officials insist that move would be highly unlikely.

Donald Trump recently called “impeachment” a “dirty, filthy, disgusting word,” but his continued stonewalling of legitimate congressional oversight requests are moving more and more House Democrats to embrace that “filthy” concept. That was the very point made by Rep. Ted Lieu of California, a progressive Democrat who sits on the House Judiciary Committee during our recent conversation on “Salon Talks.” That committee would be the starting point for an actual impeachment inquiry of the president.

As progressive candidates continue to announce their intentions to oust corporate Democrats, a new report names 15 House Democrats to unseat in primary challenges.

Published Monday by the left-leaning group RootsAction, the new report is entitled Bad Blues: Some of the House Democrats Who Deserve to Be 'Primaried.'

The list, the report notes, "is by no means exhaustive—only illustrative."

"There may well be a Democratic member of Congress near you not included here who serves corporate interests more than majority interests, or has simply grown tired or complacent in the never-ending struggles for social, racial, and economic justice as well as environmental sanity and peace," the report notes. "Perhaps you live in a district where voters are ready to be inspired by a progressive primary candidate because the Democrat in Congress is not up to the job."
