Sen. Bernie Sanders (I-Vt.) apparently doesn't agree with the climate policy presented by his colleague, Sen. Amy Klobuchar (D-Minn.)

When asked during Tuesday's Democratic debate why she wouldn't immediately ban fracking if elected president, Klobuchar said she considers natural gas a necessary "transition fuel," which can help the U.S. net zero carbon emissions in the long run. Sanders, who supports a fracking ban, simply shook his head.

Seconds later, when Klobuchar made the claim that the candidates on stage share similar climate and energy plans, Sanders was caught on camera mouthing "no."

Klobuchar's stance on fracking and natural gas, though, did receive some praise from the right. Tim O'Donnell

Jay Sekulow apparently missed a few memos from the Trump administration.

Sekulow, who is serving as President Trump's outside lawyer in the Senate's impeachment trial, argued Tuesday that disputes between the White House and Congress are "why we have courts." But as the Department of Justice has repeatedly argued, including as recently as last month, that's not what this administration believes.

Arguments began Tuesday in the impeachment trial of Trump, during which House impeachment managers and Trump's defense team debated Republican-back rules for the trial. That's when Sekulow took shots at House Democrats who brought the charges against Trump, saying they should've let the courts rule on their subpoenas for documents and testimony from Trump administration officials before moving forward with impeachment. If they took issue with Trump claiming executive privilege to block those subpoenas, well, "it is why we have courts," Sekulow said.

Yet in December court filing regarding a House lawsuit against former White House Counsel Don McGahn, the Trump administration argued the opposite is true. Asking the court to "weigh in" on the subpoena "when political tensions are at their highest levels" reveals "why this sort of interbranch dispute is not one that has 'traditionally thought to be capable of resolution through the judicial process,'" the DOJ wrote.

Sekulow also alleged the Mueller report cleared Trump of collusion, which isn't a crime and not something former Special Counsel Robert Mueller even investigated. And as for Sekulow's claim that House Republicans weren't allowed into closed-door impeachment hearings, well, 48 of them were. Kathryn Krawczyk

The Senate's impeachment trial of President Trump is underway, but it's already received a last-minute rule change.

Senate Majority Leader Mitch McConnell (R-Ky.) on Monday unveiled the proposed impeachment trial rules, under which each side would have 24 hours over two days for opening arguments. This proposal quickly drew criticism from Democrats, as it could see sessions stretching past midnight, beyond the point where most people would be able to watch.

But this rule was modified Tuesday with a proposal under which opening arguments for each side would still last 24 hours, but over three days rather than two, NBC News reports. This would see the Senate's sessions wrapping up around 9 p.m rather than after midnight, and it could extend the length of the trial by two days, Politico notes. CNN's Kevin Liptak reports this change apparently came together quite quickly, as the resolution received a handwritten update.

But although Democrats were critical of the rules, CNN reports the changes were actually "the result of concerns from moderate Republicans." A spokesperson for Sen. Susan Collins (R-Maine) confirmed to NBC that she was among these Republicans who complained, saying, "She thinks these changes are a significant improvement." Another rule change allows for evidence to be submitted automatically unless there are objections.

CNN's Kaitlan Collins further reports that the White House pushed for the two-day timetable, as "officials were concerned they may not get to make their full arguments this week with the 3-day period." These White House officials, Collins reports, "think it's better if all their arguments are made consecutively, instead of possibly being broken up and stretching into next week." Besides, as CBS' Kathryn Watson noted, "Most senators want to sit silently for 12 hours without moving/eating/looking at their phones as much as anyone else." Brendan Morrow

The fact checkers came out quickly in response to White House Counsel Pat Cipollone on Tuesday.

In his opening remarks at President Trump's Senate impeachment trial, Cipollone argued that Trump faced unprecedented violations of due process while the House was conducting its impeachment inquiry last year. He said House Democrats were running the investigation from a "basement" and accused House Intelligence Committee Chair Adam Schiff (D-Calif.) of blocking his Republicans colleagues from entering the Sensitive Compartmented Information Facility.

As it turns out, GOP lawmakers on the House Intelligence, Foreign Affairs, and Oversight Committees were indeed welcome to join those proceedings, and while many of them chose not to attend, several participated. Tim O'Donnell

President Trump is heavy on the plans and light on the specifics.

In a wide-ranging interview with The Wall Street Journal on Tuesday, Trump confirmed he was considering adding more countries to his travel ban, said he would impose tariffs on European automobiles, and added he was working on a middle-class tax cut. Not that he said which ones, when that would happen, or just what the cut entailed, respectively.

Reports first indicated the Trump administration was planning an addition to its travel ban earlier this month. Trump told the Journal his administration does have plans to add more countries to the list later this month, but wouldn't say more. He also said his administration is "looking at many different things" when it comes to his longstanding — and now faded — push to oust Venezuelan leader Nicolás Maduro.

Trump went on to say he's still working on a trade agreement with the EU, saying "I'm going to put tariffs on them if they don't make a deal that's a fair deal." He was asked when that would happen but didn't answer, just saying "they know what the deadline is." And as for policies back in the U.S., Trump said "we're talking a fairly substantial… middle-class tax cut" that'll be revealed in 90 days. The plan's implementation dependent on him being reelected, Republicans holding the Senate, and the GOP taking back the House — the third bit being very unlikely in a presidential election year.

The Wuhan virus, which broke out in China last month and has so far infected more than 300 people and killed six, has reportedly reached U.S. shores, a federal source told CNN.

The Centers for Disease Control and Prevention is expected to announce Tuesday that a person in Washington state has been infected, making the U.S. the sixth country to experience the outbreak of the respiratory illness, along with China, Taiwan, Japan, Thailand, and South Korea. The patient was hospitalized with pneumonia last week after having traveled to eponymous Wuhan, China, where the outbreak appears to have originated at a seafood and poultry market, The New York Times reports.

A lot remains unknown about the virus, although the latest development strengthens the hunch that it spreads from person to person. One of the most pressing questions, Dr. William Schaffner, a professor of preventative medicine and infectious diseases at Vanderbilt University Medical Center, told the Times, is how frequent that human-to-human transmission is.

Ozzy Osbourne has revealed he's battling Parkinson's disease, opening up about his diagnosis in an emotional new interview.

The rock star spoke in an interview with Good Morning America that aired Tuesday, saying he was diagnosed with a form of Parkinson's disease after a fall last year.

"It's been terribly challenging for us all," Osbourne said, though his wife, Sharon Osbourne, described the diagnosis as "not a death sentence by any stretch of the imagination."

Osbourne previously postponed his planned 2019 tour dates, citing his health. "Words cannot express how frustrated, angry and depressed I am not to be able to tour right now," he said at the time. He reiterated to GMA that he "can't wait" to get back on the road again. "That's what's killing me," he said. "I need it, you know."

Now that he's revealed his diagnosis, Osbourne told GMA "I feel better," adding he hopes his fans "hang on and they're there for me because I need them." Osbourne, who's set to release a new album Ordinary Man next month, also promised, "I ain't going to go anywhere yet." Brendan Morrow
