Federal prosecutors have asked the judge overseeing the prosecution of Donald Trump, Walt Nauta and Carlos De Oliveira in the Southern District of Florida to hold a hearing that could result in Mr Nauta seeking new legal representation in the case against him. Special Counsel Jack Smith’s office on Wednesday filed a motion asking Judge Aileen Cannon to schedule what is known as a “Garcia Hearing,” at which Mr Nauta would be informed that he has the right to be represented by a lawyer who does not represent any other party in the case against him. The proceeding takes its’ name from a 1975 court case, United States v. Garcia, in which an appeals court found that a defendant could use an attorney with a conflict of interest if they were properly informed as to the risks in doing so. Prosecutors said they were asking for the hearing because Mr Nauta’s attorney, Stanley Woodward, has represented or is currently representing three other people who may be called to testify against the longtime Trump aide and his co-defendants when the case against them goes to trial in May 2024. They explained that the hearing is needed because “ an attorney who cross-examines a former or present client inherently encounters divided loyalties,” and suggested that Judge Cannon could “procure” an independent attorney to be present at the hearing to advise Mr Nauta should he wish to speak with them. The special counsel’s office said Mr Woodward, who is paid by Mr Trump’s Save America Political Action Committee, represents seven persons who have been questioned during the government’s probe into the ex-president’s alleged mishandling of classified information. Specifically, they said the individuals include the Mar-a-Lago IT director referenced in the indictment of Mr Trump, Mr Nauta and Mr De Oliveira as “Trump Employee 4” as well as two other Trump aides who worked for the ex-president “during his presidency and afterwards”. Prosecutors also noted that they had previously told Mr Woodward in February and March of this year that his representation of the IT supervisor constituted a conflict because the employee would give evidence that was damaging to Mr Trump and Mr Nauta. The IT worker subsequently obtained a different attorney in early July, just a few weeks before the government obtained a superseding indictment of the ex-president and Mr Nauta and added Mr De Oliveira as a defendant in the case using the worker’s testimony. Continuing, they said Mr Woodward’s representation of the potential witnesses raises a conflict of interest because it “may result in the attorney’s improper use or disclosure of the client’s confidences during the cross-examination” or result in the attorney “pulling his punches” during cross-examination of the witnesses to protect the client or his own personal interests. “Where, as here, a potential conflict arises from an attorney’s simultaneous or successive representation of a defendant and a potential witness, a Garcia hearing is warranted. Nauta should be thoroughly advised of the potential conflicts and attendant risks,” they said. Prosecutors added that the two witnesses other than the Mar-a-Lago IT worker should also attend the hearing so they can be advised of the risks of having Mr Woodward as an attorney. A response to the government motion by Mr Nauta’s legal team is due on 16 August. Read More Trump has now been indicted for a 3rd time.

Special glasses marketed to filter out blue light likely do not make any difference to sleep quality or eye strain from computer use, according to a new review of studies. Blue-light blocking spectacles have been increasingly recommended, often by optometrists, since the early 2000s. Eye patients are frequently prescribed these lenses in many parts of the world with a range of marketing claims existing about their potential benefits. Some of these claims include that the special glasses may reduce eye strain associated with digital device use, improve sleep quality, and also protect the retina from light-induced damage. However, researchers, including those from the University of Melbourne in Australia, say there is “substantial debate” about whether blue-light filtering spectacle lenses have merit in ophthalmic practice. The research, published in the journal Cochrane Database of Systematic Reviews, assessed data from 17 clinical trials on the benefits offered by these glasses for improving visual performance, providing protection to the retina, and improving sleep quality. The review assessed data from individual studies from six countries, each including five to 156 participants, and the period of time over which the lenses were assessed ranging from less than one day to five weeks. Researchers found that there may be “no short-term advantages” with using blue-light filtering spectacle lenses to reduce visual fatigue associated with computer use, compared to non-blue-light filtering lenses. They say it is also currently unclear whether these lenses affect vision quality or sleep-related outcomes. The research review could also draw no conclusions about any potential effects on retinal health in the longer term. “People should be aware of these findings when deciding whether to purchase these spectacles,” study co-author Laura Downie said. “Our findings do not support the prescription of blue-light filtering lenses to the general population. These results are relevant to a broad range of stakeholders, including eye care professionals, patients, researchers and the broader community,” Dr Downie added. However, scientists said the quality and duration of the individual studies part of the review also needs to be considered. “High-quality, large clinical research studies with longer follow-up in more diverse populations are still required to ascertain more clearly the potential effects of blue-light filtering spectacle lenses on visual performance, sleep and eye health,” Sumeer Singh, another author of the study, said. The potential mechanisms by which these lenses might help with eye strain, sleep, and protecting the retina are also unclear, scientists say. “The amount of blue light our eyes receive from artificial sources, such as computer screens, is about a thousandth of what we get from natural daylight,” Dr Singh said. “Filtering out higher levels of blue light would require the lenses to have an obvious amber tint, which would have a substantial effect on colour perception,” he added. But the new research did not find any consistent reports of adverse side effects from using blue-light filtering lenses.
