‘Not a Bonafide Counterintelligence Investigation’: Barr Slams Comey’s Handling of Flynn Probe

Attorney General Bill Barr explained that the FBI did not conduct “a bonafide counterintelligence investigation” in the case that led former Trump national security adviser Michael Flynn to plead guilty to federal investigators in 2017.Barr, speaking in an exclusive interview with CBS News after the Justice Department dropped its case against Flynn on Thursday, said that his review of the case found Bureau investigators laid “a perjury trap” for Flynn in a January 2017 White House interview.“They didn’t warn him, the way that would usually be required by the Department, they bypassed the Justice Department, they bypassed the protocols at the White House, and so forth,” Barr stated. “These were things that persuaded me that there was not a legitimate counterintelligence investigation.”Former FBI director James Comey admitted in a December 2018 interview that he “sent” the agents to interview Flynn, adding that it was “something I probably wouldn’t have done or maybe gotten away with in a more organized administration.”In its Thursday court filing, the Justice Department explained that it was “not persuaded” that Flynn’s interview, which led to his guilty plea for lying to FBI agents Peter Strzok and Joe Pientka, had proper predication and was materially relevant.Comey tweeted his disappointment, following the decision, saying "the DOJ has lost its way."> The DOJ has lost its way. But, career people: please stay because America needs you. The country is hungry for honest, competent leadership.> > -- James Comey (@Comey) May 7, 2020Barr pointed to recently-released information that showed the FBI moved to close its surveillance of Flynn after finding “no derogatory information” about the retired general’s contacts with Russians, only for Strzok to keep the case open, leading to the eventual interview.“They were closing the investigation, in December [2016], they started that process and on January 4, they were closing it. When they heard about the phone call, which the FBI had the transcripts to — there was no question as to what was discussed, the FBI knew exactly what was discussed — and General Flynn, being the former director of the DIA, said to them, ‘you listen to everything, you know what was said,’” Barr explained.“So there’s no mystery about the call, but they initially tried some theories of how could open another investigation, which didn’t fly, and then they found out that they had not technically closed the earlier investigation, and they kept it open for the expressed purpose of trying to catch — lay a perjury trap — for General Flynn,” he added. A different filing released last week showed handwritten notes from an FBI official that questioned if the goal of Flynn’s White House interview was “to get him to lie, so we can prosecute him or get him fired.”Barr also did not comment on whether those that sought to entrap Flynn would face criminal charges, pointing to U.S. Attorney John Durham’s probe into the origins of the Trump-Russia investigation and saying his team was “in the middle” of “looking at the whole pattern of conduct.”“I’m going to wait until all the evidence is [in], and I get their recommendations as to what they found and how serious it is. But, if we were to find wrongdoing, in the sense of any criminal act, obviously we would follow through on that,” Barr said. “But again, just because something may even stink to high heaven, and appear to everyone to be bad, we still have to apply the right standard and be convinced that there is a violation of a criminal statute and that we can prove it beyond a reasonable doubt. The same standard applies to everybody.”

The Australian government has told the International Criminal Court it should not investigate alleged war crimes in Palestine because Palestine is “not a state”, arguing the court prosecutor’s investigation into alleged attacks on civilians, torture, attacks on hospitals, and the use of human shields, should be halted on jurisdictional grounds.

Australia was lobbied to make the submission to the court by Israel, which is not a party to the court. But the office of the prosecutor has rejected Australia’s argument, saying it had not formally challenged Palestine’s right to be a party to the court before.

Denmark must investigate foreign bribery more proactively

Denmark’s enforcement of its foreign bribery laws has been weak. Only 13 foreign bribery allegations have surfaced, and sanctions have been imposed in just one case that falls under the Convention. Law enforcement authorities have not been sufficiently proactive, and cases have been prematurely closed without complete investigations. Denmark must take more investigative steps and make greater efforts to gather evidence from abroad.

Microsecond time-resolved X-ray diffraction for the investigation of fatigue behavior during ultrasonic fatigue loading

A new method based on time-resolved X-ray diffraction is proposed in order to measure the elastic strain and stress during ultrasonic fatigue loading experiments. Pure Cu was chosen as an example material for the experiments using a 20 kHz ultrasonic fatigue machine mounted on the six-circle diffractometer available at the DiffAbs beamline on the SOLEIL synchrotron facility in France. A two-dimensional hybrid pixel X-ray detector (XPAD3.2) was triggered by the strain gage signal in a synchronous data acquisition scheme (pump–probe-like). The method enables studying loading cycles with a period of 50 µs, achieving a temporal resolution of 1 µs. This allows a precise reconstruction of the diffraction patterns during the loading cycles. From the diffraction patterns, the position of the peaks, their shifts and their respective broadening can be deduced. The diffraction peak shift allows the elastic lattice strain to be estimated with a resolution of ∼10−5. Stress is calculated by the self-consistent scale-transition model through which the elastic response of the material is estimated. The amplitudes of the cyclic stresses range from 40 to 120 MPa and vary linearly with respect to the displacement applied by the ultrasonic machine. Moreover, the experimental results highlight an increase of the diffraction peak broadening with the number of applied cycles.

Investigation of growth characteristics and semimetal–semiconductor transition of polycrystalline bis­muth thin films

The preferred orientation growth characteristics and surface roughness of polycrystalline bis­muth (Bi) thin films fabricated on glass substrates using the molecular beam epitaxy method were investigated at temperatures ranging from 18 to 150°C. The crystallization and morphology were analyzed in detail and the polycrystalline metal film structure-zone model (SZM) was modified to fit the polycrystalline Bi thin film. The boundary temperature between Zone T and Zone II in the SZM shifted to higher temperatures with the increase in film thickness or the decrease of growth rate. Furthermore, the effect of the thickness and surface roughness on the transport properties was investigated, especially for Bi thin films in Zone II. A two-transport channels model was adopted to reveal the influence of the film thickness on the competition between the metallic surface states and the semiconducting bulk states, which is consistent with the results of Bi single-crystal films. Therefore, the polycrystalline Bi thin films are expected to replace the single-crystal films in the application of spintronic devices.

Development of a scanning soft X-ray spectromicroscope to investigate local electronic structures on surfaces and interfaces of advanced materials under conditions ranging from low vacuum to helium atmosphere

A scanning soft X-ray spectromicroscope was recently developed based mainly on the photon-in/photon-out measurement scheme for the investigation of local electronic structures on the surfaces and interfaces of advanced materials under conditions ranging from low vacuum to helium atmosphere. The apparatus was installed at the soft X-ray beamline (BL17SU) at SPring-8. The characteristic features of the apparatus are described in detail. The feasibility of this spectromicroscope was demonstrated using soft X-ray undulator radiation. Here, based on these results, element-specific two-dimensional mapping and micro-XAFS (X-ray absorption fine structure) measurements are reported, as well as the observation of magnetic domain structures from using a reference sample of permalloy micro-dot patterns fabricated on a silicon substrate, with modest spatial resolution (e.g. ∼500 nm). Then, the X-ray radiation dose for Nafion® near the fluorine K-edge is discussed as a typical example of material that is not radiation hardened against a focused X-ray beam, for near future experiments.
