Senate Majority Leader Mitch McConnell has made it clear he doesn't want to negotiate with Democrats on health care — but he's no longer dismissing the option. Here's what he said today at a Rotary Club lunch in Kentucky when asked whether he might need bipartisan cooperation to pass a health care bill, per AP:

"If my side is unable to agree on an adequate replacement, then some kind of action with regard to the private health insurance market must occur ... We've got the insurance markets imploding all over the country, including in this state."

Between the lines: Just two weeks ago, McConnell told reporters that he'd rather not deal with Senate Minority Leader Chuck Schumer because Republicans wouldn't be able to achieve any of their health care priorities, including rewrites of Medicaid and insurance rules. But he's not blind to the spectacle of Republicans running away from the health care bill — and his comments suggest he knows he may need a backup plan.

Walter Shaub, who submitted his resignation Thursday as director of the Office of Government Ethics, was asked by CBS News whether he believes the Trump family is using the presidency to enrich themselves. His answer:

"I can't know what their intention is. I know that the effect is there's an appearance that the businesses are profiting from his occupying the presidency, and appearance matters as much as reality. So even aside from whether or not that's actually happening we need to send a message to the world that the United States is going to have the gold standard for an ethics program in government, which is what we've always had."

Why it matters: Potential conflicts of interest surrounding Trump caused a major stir shortly after he took office, but have been on the backburner for a while. It's far from clear that Shaub's resignation will do much to revive the issue — Trump for one has long contended that most Americans don't care.

The CDC says American doctors have curbed their opioid prescription rate by 18% from 2010 to 2015, but are still prescribing three times as many opioids as their European counterparts, per NPR.

"We are still massively overprescribing," Andrew Kolodny, an addiction specialist at Brandeis University, told NPR. And the average length of prescriptions has risen from 13 to 18 days between 2010 and 2015. Longer periods of use increase chances of addiction.

Rank-and-file Republicans are continuing to distance themselves from their party's unpopular health-care bill as the July 4 recess nears its end.

• Sen. John Hoeven told constituents he ""doesn't support the bill as it stands," but believes the Senate will get to something better, according to the Bismarck Tribune.
• Sen. Jerry Moran, facing a crowd with a lot of health-care questions, also reiterated his opposition to the most recent Senate bill, the Topeka Capital-Journal reported. Moran said he wants a more bipartisan process and to preserve protections for people with pre-existing conditions.

Police in Hamburg, Germany have used water cannons to disperse protesters after being attacked with stones and bottles, per AP. Thousands of demonstrators have gathered in Hamburg for the G20 summit, most of them peaceful, but police say a group of masked anti-capitalist protesters vandalized a car and threw objects.
