Twitter's move comes just a month after YouTube banned Duke's channel in late June for violating its "strict policies prohibiting hate speech."

Trump took to Twitter on early Thursday morning to call for a delay of the 2020 U.S. Presidential election, citing mail-in voting fraud. "With Universal Mail-In Voting (not Absentee Voting, which is good), 2020 will be the most INACCURATE & FRAUDULENT Election in history," so President Trump, adding it would be an "embarrassment to the USA."

He ended the tweet by suggestion to "delay the Election until people can properly, securely and safely vote???."

Dr. Anthony Fauci, NIAID Director and WH Coronavirus advisor, reports that there is no valid scientific data that shows hydroxychloroquine is an effective treatment for Covid-19.

"You look at the scientific data and the evidence. And the scientific data ... on trials that are valid, that were randomized and controlled in the proper way, all of those trials show consistently that hydroxychloroquine is not effective in the treatment of coronavirus disease or Covid-19," Fauci told MSNBC just a day after President Trump promoted hydroxychloroquine as a working treatment. Trump had claimed that many doctors thought the drug was "extremely good" and that it was safe to take. As of now, there is no FDA-approved drug for the treatment of Covid-19.

Mars is getting crowded. On July 23, China has launched its Tianwen-1 mission atop a Long March 5 rocket from Wenchang spaceport on Hainan Island. The Tianwen-1 Mars rover – or "Questions to Heaven" – is scheduled to arrive in Martian orbit in February and land on the surface of the Red Planet two or three months later.

"Specifically, the scientific objectives of Tianwen-1 include: (1) to map the morphology and geological structure, (2) to investigate the surface soil characteristics and water-ice distribution, (3) to analyze the surface material composition, (4) to measure the ionosphere and the characteristics of the Martian climate and environment at the surface, and (5) to perceive the physical fields (electromagnetic, gravitational) and internal structure of Mars," members of a recent Nature Astronomy paper wrote.

Fifteen US mayors have addressed a letter to Attorney General William Barr and Acting Secretary of the Department of Homeland Security Chad Wolf opposing the use of federal federal law enforcement with "no oversight" against protesters. The letter is calling the act of deploying federal forces against protesters an "abuse of power" and is demanding the withdrawal of "extraordinary federal law enforcement and military presence" from Portland and other American cities.

"These are tactics we expect from authoritarian regimes -- not our democracy [...] The murder of George Floyd in Minneapolis sparked a national uprising and reckoning. The majority of the protests have been peaceful and aimed at improving our communities. Where this is not the case, it still does not justify the use of federal forces. Unilaterally deploying these paramilitary-type forces into our cities is wholly inconsistent with our system of democracy and our most basic values," the letter, posted by Mayor Muriel Bowser, said.

The list of mayors who signed the letter is as follows: Jenny A. Durkan, Seattle; Ted Wheeler, Portland; Keisha Lance Bottoms, Atlanta; Lori Lightfoot, Chicago; Muriel Bowser, Washington DC; Quinton D. Lucas, Kansas City; Martin J. Walsh, Boston; Jim Kenny, Philadelphia; Michael Hancock, Denver; Eric Garcetti, Los Angeles; Sam Liccardo, San Jose; Libby Schaaf, Oakland; Regina Romera, Tucson; Darrell Steinberg, Sacramento; Kate Gallego, Phoenix.

Portland officials had previously stated that federal officers were working in coordination with local law enforcement but have since come out saying that "coordination was not made with Portland police" as the "federal police have their marching order."

According to Chad Wolf, federal law enforcement had only been deployed to Portland. On Monday, Trump vowed to send federal officers to other cities.

UAE's Mars Hope lift-off was a success. On Sunday the United Arab Emirates launched its Hope probe, a probe designed to orbit Mars to gather data from the Red Planet, from the Tanegashima Space Centre in Japan. The probe, which should reach March sometime in February 2021, will track day-to-night cycles of the planet's weather over the period of a Martian year which equals 687 days on Earth.
