Friday night’s cyberattack is “the most significant, successful attack on energy infrastructure” known to have occurred in the U.S., according to Politico.

Colonial Pipeline carries 45% of fuel supplies in the eastern U.S. Some 5,500 miles of the pipeline has been shut down in response to the attack.

While gasoline and diesel prices aren’t expected to be impacted if pipeline operations resume in the next few days, fuel suppliers are becoming “increasingly nervous” about possible shortages, Bloomberg reports.

Colonial said in a statement Sunday while its main fuel lines remained offline, some smaller lines between terminals and delivery points were now operational.

He said “We will bring our full system back online only when we believe it is safe to do so and in full compliance with the approval of all federal regulations”

The US said it’s “working with” fuel pipeline operator Colonial Pipeline to try and restart operations as soon as possible.

The regional emergency declaration by the Department of Transportation’s Federal Motor Carrier Safety Administration is so that fuel supply lines can be kept open.

The emergency declaration covers Alabama, Arkansas, D.C., Delaware, Florida, Georgia, Kentucky, Louisiana, Maryland, Mississippi, New Jersey, New York, North Carolina, Pennsylvania, South Carolina, Tennessee, Texas and Virginia.

The DoT agency said in a statement the declaration “addresses the emergency conditions creating a need for immediate transportation of gasoline, diesel, jet fuel, and other refined petroleum products and provides necessary relief.”

The attack is a significant breach of critical infrastructure and comes on the heels of multiple other major cyberattacks on both U.S. companies and the federal government in recent months by foreign actors.

Henderson State University chemistry professors Terry Bateman, 45, and Bradley Rowland, 40, were charged Friday with the manufacture of methamphetamine and the use of drug paraphernalia, Fox 16 Little Rock reported.

Students suspected meth may have been involved when a chemical spill closed the college’s science building in October for three weeks, the station reported.

“I heard rumors about it and I thought it might be true, but now that they actually got arrested I’m like wow,” sophomore Ebuka Okeke told the station. “That’s something else.”

The arrests were announced by the Clark County Sheriff’s Office, the station reported.

Bateman and Rowland were subjects of an investigation with Henderson State University police, Fox 16 reported.

They were placed on administrative leave three days after the chemical spill, according to the station.

A Henderson spokeswoman told the station the science building reopened after a clean-up.

The university is located in Arkadelphia.

Ashley and Erin Watt were on a kayaking trip, heading down the Arkansas River in August, when they noticed a massive skull buried nose down in a sandbar, the Kansas Department of Wildlife, Parks and Tourism said Tuesday in a news release.

The curious sisters then pulled the exciting discovery out of the sand, only to find a uniquely shaped skull with a set of sharp carnivorous teeth. It was later determined the skull measured 16 inches long by 8.5 inches wide, the agency added.

Ashley, a former high school agriculture teacher, and Erin, an animal science student at West Texas A&M University, determined they likely found a bear skull and shared photos on Facebook.

News of the sisters’ discovery eventually reached Dr. Reese Barrick and Mike Everhart, paleontologists at the Sternberg Museum of Natural History in Hays, Kan., the agency said.

The scientists verified that the sisters had found a bear skull that may be over 200 years old, Ashley wrote on Facebook.

However, its fossilized appearance left the experts questioning whether it belonged to a modern grizzly or a more primitive species.

“The bear skull was washed out of the same river sediments that routinely produce the skulls and bones of the American bison, some of which could date back as far as the last Ice Age,” said Everhart, the Adjunct Curator of Paleontology at the museum.

“Whether it is hundreds or thousands of years old, the skull gives us a better insight into the richness of life on the plains before Western man,” he said.

Grizzly bears were native to Kansas and believed to have roamed throughout the state until they were all hunted and killed in the mid-1800s, the agency said. While there have been historical accounts of grizzly bears in Kansas, the agency said the skull could mark the first piece of physical evidence of their former presence, pending species verification.

Everhardt said the skull was one of three of its type to have been found in Kansas, the last of which was discovered in the 1950s, Ashley wrote on Facebook.

The sisters have donated the skull to the Sternberg Museum.

Authorities say a 52-year-old Florida man was found dead Thursday in his stranded pickup truck along Interstate 10 near Beaumont, which is near Texas’ border with Louisiana. Jefferson County spokeswoman Allison Getz said that although floodwaters seeped into Mark Dukaj’s truck, investigators don’t believe he drowned, though they do believe his death is storm-related. An autopsy will determine the cause.

Hundreds of homes and other buildings in the Houston area have been damaged by the storm, bringing back unpleasant memories of Hurricane Harvey — which dumped more than 50 inches of rain on the area two years ago. Imelda, the first named storm to impact the area since then, has deposited more than 40 inches of rain in some spots as it churned across a region extending east from Houston to the Louisiana border.

Texas Gov. Greg Abbott has already declared a state of disaster for the counties impacted by Imelda  and officials in Harris County, which is home to Houston, were trying to determine if millions of dollars in uninsured losses were enough to trigger a federal disaster declaration.

The heaviest rainfall had ended by Thursday night in Southeast Texas, but forecasters warned that parts of northeast Texas, Arkansas, Oklahoma and Louisiana could see flash flooding as Imelda’s remnants shifted to the north.

Officials say two of the deaths from Imelda happened in the Houston area: an unidentified man in his 40s or 50s who drowned Thursday while driving a van through 8-foot-deep floodwaters and a man whose body was found in a ditch Friday and is believed to have drowned.

Lake County Sheriff Oscar Martinez reported that Madison Eddlemon had been located, the Times of Northwest Indiana reported.

“This positive could only have been possible through the mutual cooperation of both state and federal agencies,” Martinez said, according to the paper.

Madison was believed to be in “extreme danger,” possibly abducted by a man who has been accusing of stalking her, according to police.

Alexander Martin Curry-Fishtorn, 22, was also located and taken into custody, the paper reported. Martinez said he faces numerous charges.

Madison disappeared Saturday morning in Crown Point, Ind., a city roughly 50 miles southeast of Chicago, according to the National Center for Missing and Exploited Children. Her family last spoke to her the night before.

Her car was later found abandoned, with a window cracked open and “some of her belongings” inside, the Crown Point Police Department said.

Her family believed she was with Curry-Fishtorn, of St. John, who had an order of protection filed against him for stalking Eddlemon, according to investigators.

“All in for Senator Steve Daines as he proposes an Amendment for a strong BAN on burning our American Flag. A no brainer!,” the president wrote in a Twitter message Saturday.

The proposal is being sponsored in the Senate by Sens. Steve Daines of Montana and Kevin Cramer of North Dakota and in the House by Rep. Steve Womack of Arkansas. It calls for the United States Constitution to be amended so Congress would have “constitutional authority to ban the desecration of the United States flag.”

“The American Flag is a symbol of freedom – and it should always be protected,” Daines wrote Friday.

Added Cramer: “A flag worth dying for is a flag worth protecting.”

“Adding a Constitutional amendment to protect this symbol of freedom and liberty is not an attack on another Constitutional amendment,” he continued, “rather, it is an affirmation of the unifying principles our nation stands for.”

The amendment would be very important because the Supreme Court has ruled in the past that flag-burning is a form of free speech protected by the First Amendment.

The new proposal was reintroduced on Friday, which was Flag Day – and coincidentally President Trump’s 73rd birthday.

According to the Washington Times, amendments can be added to the Constitution in that if two-thirds of both the House and Senate agree on a proposal and then three-fourths of the states ratify it, or if two-thirds of state legislatures call a convention to propose changes to the Constitution, and then three-fourths of the states ratify the change.
