It's Monday, Aug. 26, 2019. Let's start here.
1. Second thoughts?
"Yeah, sure," Trump told reporters. "I have second thoughts about everything."
Just hours after the president appeared to take a softer tone toward China, White House Press Secretary Stephanie Grisham attempted to clarify his remarks, saying Trump's words were "greatly misinterpreted" and he "regrets not raising the tariffs higher."
Treasury Secretary Steven Mnuchin suggested Trump had misheard the question and told ABC News Chief White House Correspondent Jonathan Karl that higher tariffs aren't on the table, "But if China retaliates again, that's obviously an option the president can consider."
The mixed messages have added to the uncertainty surrounding the president's economic policies as allies at the summit warned him about the global ramifications of his trade war.
2. Hong Kong chaos
Police in Hong Kong fired warning shots and used tear gas in Sunday clashes with thousands of pro-democracy protesters, some of whom hurled bricks and hard objects, marking an escalation of violence in the city.
Dozens of demonstrators were arrested and 15 officers were injured in the chaos, according to police.
"This is not being controlled, it's not being contained," ABC News Senior Foreign Correspondent Ian Pannell says on "Start Here" today. "In fact the opposite, it's getting worse."
3. Trump challenger
Joe Walsh, a conservative radio host and former Republican congressman, has launched a primary challenge against the president.
Speaking exclusively with ABC News Chief Anchor George Stephanopoulos on ABC's "This Week," Walsh argued conservatives should have an alternative to Trump, calling him "unfit" and "a child."
The one-term congressman's campaign faces an uphill climb against Trump's overwhelmingly high approval rating among Republicans, but ABC News' Rachel Scott says Walsh's run could encourage other primary challengers, "If someone like Joe Walsh starts getting pick-up in a key primary state like New Hampshire, maybe others will think they have a chance too."
In the meantime, the Trump campaign's communications director is dismissing Walsh's bid, telling ABC News: "Whatever."
4. Landmark verdict
An Oklahoma judge is set to issue a landmark ruling today over claims that Johnson & Johnson fueled the state's opioid crisis.
In a $17 billion lawsuit, Oklahoma Attorney General Mike Hunter has accused the drugmaker of using deceptive marketing to downplay the risks of opioids. Johnson & Johnson, which produced the Duragesic and Nucynta painkillers under its Janssen Pharmaceuticals subsidiary, has denied any mismarketing of its painkillers or wrongdoing.
The verdict could open the door for similar opioid cases if the judge rules in favor of the state, according to ABC News' Aaron Katersky, but if Johnson & Johnson prevails, he says, "It could be much harder to hold any one company liable for an epidemic that states believe the company should be on the hook for."
