Democrats argued that President Donald Trump sought a phony investigation of a political rival and pursued a discredited conspiracy theory about Ukraine, while restless senators played with a new toy Thursday during Trump's impeachment trial. Democrats said there was no evidence that former Vice President Joe Biden did anything improper in dealings with Ukraine. Republicans outside the chamber challenged Democrats' argument and pledged to find out more about Biden and his son’s dealings in Ukraine. Meanwhile, senators found a new outlet to focus their attention: fidget spinners handed out by North Carolina Sen. Richard Burr.Chief justice's admonishment followed a note from CollinsSupreme Court Chief Justice John Roberts' admonishment to House impeachment prosecutors and President Donald Trump's defense team followed a note written by Sen. Susan Collins of Maine. Collins' spokeswoman confirms that the Republican penned the note after House Judiciary Committee Chairman Jerry Nadler's comment about a “cover-up” by Senate Republicans for Trump. After receiving the note, Roberts admonished both sides around 1 a.m. Wednesday. Collins indicated afterward that she'll make her decision on impeachment on the facts that are presented, and said Nadler's comments won't affect her decision.Schiff sets tone with appeals to SenateRep. Adam Schiff is the face of the House’s impeachment case against President Donald Trump. Though he has six managers by his side, Schiff is setting the tone, working methodically to convince the Senate Trump deserves to be removed from office. Schiff told The Associated Press in an interview Thursday it is like he is “introducing myself to a number of the senators” at Trump's impeachment trial. He said many Republicans are “finding I'm not the demon” that he's often portrayed to be. Republicans were complimentary of Schiff but said they learned nothing new about the case against the president. 1951

Defense Secretary James Mattis resigned Thursday, a day after President Donald Trump's plans to withdraw troops from Syria became public."Because you have the right to have a Secretary of Defense whose views are better aligned with yours on these and other subjects, I believe it is right for me to step down from my position," Mattis wrote in his letter."One core belief I have always held is that our strength as a nation is inextricably linked to the strength of our unique and comprehensive system of alliances and partnerships. While the US remains the indispensable nation in the free world, we cannot protect our interests or serve that role effectively without maintaining strong alliances and showing respect to those allies," he added.Trump first announced Mattis' departure in a tweet."General Jim Mattis will be retiring, with distinction, at the end of February, after having served my Administration as Secretary of Defense for the past two years," Trump tweeted.Trump touted the "tremendous progress" that has been made during Mattis' tenure at the helm of the Defense Department and thanked Mattis for his service.Trump said a successor "will be named shortly."Mattis and the President's other top national security advisers opposed Trump's decision to withdraw from Syria.Mattis’ resignation letter makes it clear. “My views on treating allies with respect and also being clear eyed about both malign actors and strategic competitors are strongly held and informed by over four decades of immersion in these issues.” 1546

Dinosaurs are no longer roaming the earth, but their tracks live on. In the foothills on the Front Range of Colorado, a story can be told from pieces of the past left behind.Dinosaur Ridge has been ranked by a panel of esteemed paleontologists as the no. 1 track site in all the U.S. One of those world-renowned paleontologists is Martin Lockley, who has spent his life studying dinosaur tracks.“You're looking at a snapshot of an ancient environment," Lockley says.In an area of just a few hundred square feet, 330 dinosaur tracks have been discovered. However, the land was very different 100 million years ago. Lockley says the giant prehistoric animals weren't a mile high in the Rocky Mountains.They were on the beach at sea level in an environment very similar to present day Gulf of Mexico.“We like to joke and call this beach-front property a 100 million years ago," Lockley says.The soft, wet, sandy land made conditions ideal for preserving tracks."If they're walking on wet sediment, like a beach or a mud flat or the shores of a lake, and it dries out, it becomes hard like concrete," Lockley explains. "And the next time there's a flood washing in more sediment, it will bury those tracks without them being eroded away."Experts believe three different dinosaurs made their mark on this patch of land. Lockley says it's possible they were migrating along what used to be a coast. It's clear the western U.S. was a popular place to be, because there are more than 120 dinosaur track sites from Kansas to Utah. Martin suggests part of the reason is less vegetation in these states means more fossilized rock is exposed.But if there are so many track sites, what makes Dinosaur Ridge the top of all track sites? Executive Director Jeff Lamontagne, with Friends of Dinosaur Ridge, says there was a list of criteria the panel considered."How many tracks there are, the variety of dinosaurs seen in the tracks, the importance of the tracks, the clarity of the tracks, the accessibility and number of visitors," Lamontagne explains.Accessibility is the main reason Dinosaur Ridge has become so highly regarded."It's right outside a major metropolitan area, and there's a major road just a quarter mile from here," he says. "It's easy to see this compared to most other dinosaur track sites in the United States and in the world."People can get so close to the tracks; in some places you can even touch them. Although the tracks have been well-preserved for millions of years, their current exposure to humans and the elements could make them erode over time.Thankfully, with current technology, scientists can scan the surface and re-create it as 3-D permanent record. They also plan to build a cover to protect the land.However, Friends of Dinosaur Ridge believe the hands-on part of the site is important for kids to continue learning about the planet's past. A past that can teach us about topics like climate change, evolution and extinction."We used to think that the dinosaurs all went extinct, but then we realized that some of them survived and evolved into birds," Lockley says.For modern-day humans, Dinosaur Ridge will continue to be an intriguing learning opportunity, reminding people we aren't the only ones to experience life on Earth."It gives you a sense of wonder to imagine these enormous beasts living, playing, dying, a hundred million years ago," Lamontagne says.********************************************If you'd like to reach out to the journalist for this story, email elizabeth.ruiz@scripps.com 3540
