Sen. Marco Rubio (R-Fla.) is voting for you know who in the presidential election. Though Rubio didn't come right out and say that he'd be voting for his former rival Donald Trump, it was heavily implied in his tweets Friday where he said that come November, not only will he not be voting for Hillary Clinton, but he also won't be abstaining from voting. That leaves just one other option:

Rubio followed up that tweet with emphasis on the fact that his change of heart has more to do with preventing Hillary Clinton from becoming president than suddenly loving Trump:

Just months ago, Rubio was chastising Trump for his supposedly little hands, calling him everything from an "embarrassment" to a "person that has no ideas of any substance on the important issues." So far, his supporters haven't been thrilled with his changed tone on Trump:

The true test for Rubio's new alliance will be whether he sticks with his original plan to sit out on the Senate race because a "real good friend" of his from Florida is now running, or whether he heeds Trump's advice and runs. Becca Stanek

Boeing is reportedly attempting to cut hours off airborne testing for its new 777X airplane by using computer models to simulate flight conditions before presenting the results to the U.S. Federal Aviation Administration for certification, two people with direct knowledge of the strategy told Reuters, who was not able to confirm when Boeing decided to move forward with the plan.

The move would reportedly slash high development costs associated with physical safety testing, but it remains to be seen whether the FAA would allow the company to eliminate some of the physical tests. Boeing is currently the subject of probes by regulators and U.S. lawmakers after two of its 737 Max airplanes crashed in Ethiopia and Indonesia after a stall prevention software failure. The investigations could potentially throw Boeing's reported plans into jeopardy if they result in even more rigorous safety requirements, Reuters reports.

Five people familiar with the matter told Reuters that Boeing believes new technology and decades of testing experience have rendered some physical tests redundant for demonstrating safety. Read more at Reuters. Tim O'Donnell

President Trump is angry at The New York Times once again.

The newspaper reported on Saturday that the U.S. has enacted a more aggressive approach when it comes to cyber attacks on Russia's electric power grid. The Times conducted interviews over a three month period in which current and former officials described the previously unreported deployment of American computer code inside Russia's grid and other targets. The actions are reportedly seen as a warning to Russian President Vladimir Putin.

Two administration officials told the Times that they do not believe President Trump has been briefed about the new digital incursion strategy, while Pentagon and intelligence officials told the newspaper that they were concerned about how the president would react to the news. They also reportedly feared he would reverse the operations or discuss the classified information with foreign officials.

Trump has denied the story, even calling it a "virtual act of treason". Read more at The New York Times. Tim O'Donnell

Hundreds of thousands of demonstrators returned to the streets in Hong Kong on Sunday to protest a proposed extradition bill that would allow extradition to mainland China. The rally reportedly looks like it could reach the scale of last Sunday's protests, for which around 1 million people gathered.

The protesters were also calling for Hong Kong's Chief Executive Carrie Lam to step down, despite their understanding that she had little choice but to carry out orders from Beijing, The Associated Press reports.

Lam, reportedly with the backing of Beijing, announced on Saturday that she was suspending the extradition legislation after the protests turned violent during the week, but those opposed to the bill want it scrapped entirely. They fear the law would subject criminal suspects to possible torture and unfair trials if they are sent to China. Generally speaking, the protesters believe the bill is in conflict with Hong Kong's judicial independence and contributes to the territory's eroding freedoms. Tim O'Donnell

Tibor Nagy, the U.S. assistant secretary of state for Africa, on Friday called for an "independent and credible" investigation into the violence waged by Sudan's paramilitary security forces when they stormed a protest camp in the country's capital, Khartoum, earlier in June, The Associated Press reports.

Sudan's ruling military council, which recently ousted former autocratic President Omar al-Bashir, said it plans to announce the findings of its own investigation on Saturday. Protest organizers say over 100 people were killed by the security forces, while state authorities said the death toll was 61.

Nagy's stance echoes that of the protesters, who are hoping for an internationally-backed probe into the crackdown. The military council, which admitted that it ordered the dispersal of the sit-in, rejected that idea, as did Sudan's chief prosecutor.

Nagy added that he supports the mediation efforts by the African Union and Ethiopia's Prime Minister Abiy Ahmed, but did not say whether Washington would take any measures if the situation worsens. Tim O'Donnell

One might recall President Trump declaring in an April speech that Sen. Elizabeth Warren (D-Mass.), a 2020 presidential candidate, was "finished." Now, though, Trump's re-election campaign team considers Warren a legitimate threat and is reportedly ready to make her a target, Politico reports, based on conversations with multiple Trump advisers.

Trump aides and their allies at the Republican National Committee are reportedly digging up opposition research and deploying camera-wielding trackers in the hopes of halting Warren's momentum. They also reportedly plan to label her a "liberal extremist." Trump's advisers are reportedly concerned by Warren's disciplined style mixed with "populist-infused" speeches and her potential ability to win over suburban female voters.

The change in tune doesn't mean the Trump campaign won't continue to focus its energy on the current frontrunner, former Vice President Joe Biden, as well, Politico reports; but they're just less certain he'll face off against the president in the general election now.

Warren's prospects looked rough out of the gate, but the senator has polled well recently and has even surpassed Sen. Bernie Sanders (I-Vt.), long considered Biden's top challenger, in some of the latest tallies. Tim O'Donnell

It's unlikely to make a difference in outcome, but Sen. Susan Collins (R-Maine) said on Friday she will oppose one of President Trump's federal judicial nominees, anyway, The Washington Post reports.

Collins, who has opposed Trump on various occasions before, specifically cited nominee Matthew Kacsmaryk's "alarming bias against LGBTQ Americans and disregard for Supreme Court precedents," such as Roe v. Wade, as her primary reasons for doing so. Again, it would be a surprise if Collins' opposition makes any difference regarding Kacsmaryk's confirmation, but it is notable because of the senator's decision to vote to confirm Supreme Court Justice Brett Kavanaugh last year, which led her to face intense criticism from liberals, the Post reports. Collins was singled out, in particular, because of her past willingness to split from her own party.

Kacsmaryk currently serves as deputy general counsel to First Liberty Institute, which defends religious freedom issues. He also defended the right of a shop owner to refuse to bake a cake for a gay couple's union in a high-profile case three years ago, the Post reports. LGBTQ and women's rights groups reportedly "vehemently" oppose his nomination. Read more at The Washington Post. Tim O'Donnell
