Boeing has newly found that its flight simulators used to train pilots failed to precisely imitate the conditions that resulted in its MCAS anti-stall system malfunctioning, the New York Times reports.

Why it matters: Airlines are seeking ways to ensure their pilots are able to handle any malfunctions on the 737 MAX once they resume service, Axios' Andrew Freedman writes. If the simulators fail to replicate what went wrong in the two fatal crashes, then pilots won’t be able to realistically experience how to properly respond, even if the FAA does not require the use of simulators.

  • This revelation seems sure to intensify concerns about Boeing as the company angles to regain its footing and following with the Lion Air and Ethiopian Airlines crashes in its wake. Its training has been a sore spot throughout the investigation into its 737 MAX aircraft.
  • Boeing said Thursday it completed its fix to the 737 MAX. With edits to the anti-stall system, the plan is to include new pilot training as well.

What's next: Per the New York Times, regulators are in the process of determining what training will be required. The company have changes authorized by regulators, who will need to approve them before the planes can take flight again.

Acting U.S. Capitol Police chief Yogananda Pittman testified on Thursday that cellphone records show former USCP chief Steven Sund requested National Guard support from the House sergeant-at-arms as early as 12:58pm on Jan. 6, but he did not receive approval until over an hour later.

Why it matters: Sund and former House sergeant-at-arms Paul Irving clashed at a Senate hearing on Tuesday over a dispute in the timeline for when Capitol Police requested the National Guard during the Capitol insurrection.

Manhattan prosecutors reportedly obtain millions of pages of Trump's tax records

The Manhattan district attorney is now in possession of millions of pages of former President Trump's tax and financial records, CNN first reported, following a Supreme Court ruling that allowed prosecutors to enforce a subpoena after a lengthy legal battle.

Why it matters: Trump fought for years to keep his tax returns out of the public eye and away from prosecutors in New York, who are examining his business in a criminal investigation that was first sparked by hush-money payments made by Trump's former fixer Michael Cohen during the 2016 election.
