and his latest political stunt. jasmine crockett joins me from later legal trouble over its rendition of hamilton. we have a reporter who broke a story. all of that and more, is coming up. let s go straight to msnbc s garrett grumble, who is tracking the news details for us. gary good morning. good morning katie, three big developments, rising overnight on this big story. new york times is reporting an nbc news, is for one lawyer signed, back in june, saying all classified material, have been returned to the government. according to four people familiar with the matter. that s a big deal because they can speak to one of the possible crime is being investigated usc which is 15 19 or an administration of any matter. or a jurisdiction of any agency. that is one big part of the story. the second really is congress, and the heads of the intelligence, the hostages and house oversight committee sending a letter to daniel haynes. basically asking who saw these documents? how
In recent years, certain luminous extragalactic optical transients have been observed to last only a few days1. Their short observed duration implies a different powering mechanism from the most common luminous extragalactic transients (supernovae), whose timescale is weeks2. Some short-duration transients, most notably AT2018cow (ref. 3), show blue optical colours and bright radio and X-ray emission4. Several AT2018cow-like transients have shown hints of a long-lived embedded energy source5, such as X-ray variability6,7, prolonged ultraviolet emission8, a tentative X-ray quasiperiodic oscillation9,10 and large energies coupled to fast (but subrelativistic) radio-emitting ejecta11,12. Here we report observations of minutes-duration optical flares in the aftermath of an AT2018cow-like transient, AT2022tsd (the ‘Tasmanian Devil’). The flares occur over a period of months, are highly energetic and are probably nonthermal, implying that they arise from a near-relativistic

The nearby radio galaxy M87 offers a unique opportunity to explore the connections between the central supermassive black hole and relativistic jets. Previous studies of the inner region of M87 revealed a wide opening angle for the jet originating near the black hole1–4. The Event Horizon Telescope resolved the central radio source and found an asymmetric ring structure consistent with expectations from general relativity5. With a baseline of 17 years of observations, there was a shift in the jet’s transverse position, possibly arising from an 8- to 10-year quasi-periodicity3. However, the origin of this sideways shift remains unclear. Here we report an analysis of radio observations over 22 years that suggests a period of about 11 years for the variation in the position angle of the jet. We infer that we are seeing a spinning black hole that induces the Lense–Thirring precession of a misaligned accretion disk. Similar jet precession may commonly occur in other active
