UN Ambassador Nikki Haley said at a UN Security Council meeting that the “U.S. believes that Russia is responsible” for the nerve agent attack on an ex-spy in the UK.

"This is a defining moment," she said. "One member stands accused of using a chemical weapon on the sovereign soil of another. The credibility of this council will not survive if we fail to hold Russia to account."

The backdrop: These are strong remarks from Haley, particularly compared to President Trump's comments yesterday, in which he hedged on whether Russia was responsible. Her comments follow British P.M. Theresa May's decision to expel 23 Russian diplomats and call on the security council to take up the matter.

One big quote: “We take no pleasure in having to constantly criticize Russia, but we need Russia to stop giving us so many reasons to do so,” Haley said.

What Russia’s saying: “Russia had nothing to do with the incident” and said they could not pay attention to an ultimatum from the U.K. without more evidence. Russia has suggested the U.K. is afraid to have experts verify its findings on the nerve agent used.

What the U.K. is saying: The U.K. has invited the Organization for the Prohibition of Chemical Weapons to conduct an independent investigation.

Former Attorney General Jeff Sessions has lost the Republican nomination for Senate to Tommy Tuberville in Alabama in Tuesday night’s primary runoff, AP reports.

Why it matters: Sessions had been the underdog in the race against former Auburn University head football coach Tommy Tuberville, who had the backing of President Trump. Tuberville will now face off against Sen. Doug Jones (D-Ala.) in November, who is considered to have one of the most vulnerable Democratic Senate seats in the country.

Bank CEOs brace for worsening economic scenario

Wells Fargo swung to its first loss since the financial crisis — while JPMorgan Chase and Citigroup reported significantly lower profits from a year earlier — as the banks set aside billions of dollars more in the second quarter for loans that may go bad.

Why it matters: The cumulative $28 billion in loan loss provisions that banks have so far announced they’re reserving serves as a signal they’re preparing for a colossal wave of loan defaults as the economy slogs through a coronavirus-driven downturn.
