WASHINGTON — President Trump is increasingly being tested in international affairs. And those tests are largely self-inflicted.

Trump has taken big risks — elevating Kim, imposing tariffs, scuttling the Iran nuclear deal, trying to topple Maduro — to get his desired results.

Sometimes taking risks is rewarded.

And sometimes they cause you even more problems.

Republicans turn on Burr after Don Jr. subpoena

Just one day after Senate Majority Leader Mitch McConnell declared “case closed” on the Mueller report, we learned that the GOP-controlled Senate Intelligence Committee issued a subpoena for Donald Trump Jr.

And that has some Republicans furious at the committee’s chairman, Sen. Richard Burr, R-N.C.

Here’s Sen. Rand Paul, R-Ky.: “Apparently the Republican chair of the Senate Intel Committee didn’t get the memo from the Majority Leader that this case was closed...”

Here’s the former communications director of Trump’s 2016 campaign: “Such b.s. that @SenatorBurr (D-NC?) now taking marching orders from Democrats on the Senate Intel Committee & perpetuating Russia hoax.”

And here’s House Minority Leader Kevin McCarthy defending Don Jr: “@DonaldJTrumpJr has already spent dozens of hours testifying in front of Congressional committees. Endless investigations—by either party—won't change the fact that there was NO collusion. It's time to move on. It’s time to focus on ISSUES, not investigations.”

The significance of Burr’s action — and remember the Senate Intel Committee has operated in a bipartisan manner — is that it undermines the GOP talking point that this is a Democratic witch hunt (even though Robert Mueller is a Republican).

Also, the Washington Post reports that the Senate Intel Committee issued its subpoena at least a WEEK AGO, meaning that McConnell likely knew about it before he delivered his “case closed” speech.

The governing wing of the Senate GOP is getting smaller

Speaking of the Senate… Last Saturday, Sen. Mike Enzi, R-Wyo., announced he won’t run for re-election in 2020, becoming the third Republican senator to retire this cycle.

The other two retirements: Sen. Lamar Alexander, R-Tenn., and Pat Roberts, R-Kansas. (Sen. Tom Udall, D-N.M., is the Democrats’ only Senate retirement so far.)

What all three men have in common is that they come from the “governing wing” of the Senate GOP.

That doesn’t mean they’re centrists. But on crucial, must-pass legislation, they’re usually among those willing to reach across the aisle.

And it’s possible — if not likely — that the Republicans who might replace them in these red states won’t necessarily be members of the governing wing.

2020 Vision: Buttigieg is only 2020 Dem not offering staffers health care

NBC’s Josh Lederman reports that Pete Buttigieg “isn’t providing health care coverage to any of his own campaign workers, an NBC News review of his campaign spending disclosures shows.”

“Instead,” Lederman adds, “Buttigieg is providing a monthly stipend to workers to buy insurance on their own through the Obamacare exchanges, his campaign said, with plans to offer health care in the future.”

More: “The practice stands in contrast to the other leading presidential candidates this year, as Democrats have made a point of aligning their internal practices with the policies and values they are emphasizing on the campaign trail.”

Data Download: The number of the day is … 29 percent

Twenty-nine percent.

That's the share of Americans who say that it would bother them either "some" or "a lot" to hear a foreign language spoken in public, according to a new poll from the Pew Research Center.

The share who say they wouldn't be bothered at all is 47 percent.

But there are major partisan differences, particularly among whites.

For white Democrats, just 18 percent say that they'd be bothered by hearing a foreign language spoken in a public place. But for white Republicans, it's nearly half.
