President Trump’s former national security adviser John Bolton has been asked to testify before House investigators on Nov. 7, according to a copy of the request obtained by Axios. Bolton's lawyer said he would not appear voluntarily but he would accept a subpoena on Bolton's behalf, the New York Times' reports.

Why it matters: Trump's former Russia adviser Fiona Hill testified earlier this month that Bolton told a top Russia aide to notify White House lawyers about a campaign to pressure the Ukrainian government to investigate the Biden family and the 2016 election.

What they're saying: Hill said Bolton told her to alert the chief lawyer on the National Security Council that Giuliani was "cooking up" a "rogue operation" with acting White House Chief of Staff Mick Mulvaney and Gordon Sondland, the ambassador to the EU, per the Times.

  • Rep. Ro Khanna, a Democrat on the Oversight committee, said that Bolton can clarify "the extent of the president's awareness" of withholding military aid and "he can talk about his own warnings to the president."
  • Khanna added that Bolton could also speak to the president's awareness of arranging a meeting in exchange for a commitment from Ukrainian President Volodymyr Zelensky to open a political investigation.

Our thought bubble: ‪Bolton shares the same lawyer with former NSC official Charles Kupperman, who filed a lawsuit last week asking a federal judge to rule on whether he should testify given that Trump has asserted he is immune from the congressional process and instructed him not to appear.

The bottom line: Bolton could be a key witness in the inquiry. House Intelligence Chairman Adam Schiff said this week that he assumes the Trump administration will fight House investigators in court to keep Bolton from appearing.

Europe's energy reliance on Russia is a crucial shield for Putin

Cracks in the NATO alliance regarding sanctions for Russia should President Vladimir Putin order troops into Ukraine are in large part based on energy supply concerns.

Why it matters: Russia holds tremendous leverage over some European countries because it provides roughly 40% of Europe's natural gas supply. In Germany, this figure is greater than 50%.

Why the Fed might want to jolt the markets

So far, financial markets are cooperating nicely with the Federal Reserve's efforts to restrain inflation. They're doing the Fed's work for it by creating tighter financial conditions, in a distinctly non-panicky way.

  • But as the central bank's policymakers meet this week, an underlying question they face is whether the adjustment is happening too slowly.
