Presidential historian Jon Meacham says former President Richard Nixon's Watergate scandal looks a bit like what's happening today.

Meacham, who has written biographies on Thomas Jefferson and eulogized former President George H. W. Bush earlier this month, brought some historical context to MSNBC's Morning Joe Tuesday morning. He described how Nixon's downfall coincided with an ongoing investigation and falling markets — much like what President Trump is seeing right now.

In the two-year fallout after 1972's Watergate break-in, Nixon started out claiming he was "not a crook" — something that "would've fit on Twitter," Meacham noted. From there, the economy began "souring," Meacham said, suggesting the markets could be a "barometer of what's going to happen to President Trump."

Then, Meacham brought the conversation into the present day by discussing Russian efforts to influence the 2016 election in favor of Trump. "If in fact Donald Trump knew about" these efforts, that raises the "live question" of whether these actions fit "the definition of treason in the Constitution," Meacham explained. It all makes for an "existential Constitutional crisis" in which a president could be an "agent of a foreign power," Meacham added.

If you can't thank a veteran today, do the next best thing and donate to a non-veteran!

President Trump's campaign fundraising team didn't miss a beat this Veterans Day, running a Facebook ad on Monday encouraging people to say "THANK YOU, VETERANS" by donating to the president's metaphorical war chest.

Trump, who is not a veteran, famously deferred the Vietnam War draft several times.

The ad, which includes a can't-miss 25 percent off coupon, provoked criticism of the president, with veteran Mark Hertling pointing out the somewhat bizarre timing of the Trump campaign's message. A judge ordered Trump to pay $2 million last week over his alleged mishandling of funds for veterans, which were instead used for political purposes, CBS News reports.

The president also celebrated the day by attending New York City's Veterans Day parade, where he took the time to honor Gold Star families, despite his history of feuding with several of them.

Although if Trump really is burying the hatchet this Veterans Day, he should be sure to get the date right in next year's Facebook ad. Marianne Dodson

It's safe to say the Game of Thrones ending proved a little polarizing for anyone whose favorite character wasn't Bran. (Yes, we see you! All 12 of you!)

But if you were a little let down by the finale of the HBO series, take solace in the wisdom of the Mother of Dragons herself, who says expectations were so high that there's no ending that "would have made everyone happy." Emilia Clarke also says she doesn't plan to act alongside dragons again anytime soon, so temper your expectations for Last Christmas accordingly. Read more at Indiewire. Scott Meslow

For 12 seasons, Kaley Cuoco starred on The Big Bang Theory as Penny, the sunny heroine who tolerated her weird neighbors rambling endlessly about Star Trek or Magic: The Gathering.

But according to Cuoco, the character of Penny was originally conceived very differently, as a "dark, brooding unhappy woman," which — while an admittedly unconventional choice for a breezy sitcom — makes a lot more sense for a woman stuck hanging out with those guys for 12 years.

Endings don't come much more definitive than Avengers: Endgame, which saw most of the original Avengers lineup dead or retired by the time the credits rolled.

But diehard fans might have a glimmer of hope that they'll get to spend a little more time with Captain America, who is elderly but still alive at the end of the movie. "You never say never. I love the character. I don't know," said Evans in a recent interview — so I guess we can all look forward to Captain America: Getting Mad At Teens Who Tweet "OK Boomer" sometime on the horizon.

Over the weekend, the People's Choice Award for Best Reality Series went to Keeping Up with the Kardashians, which topped fellow must-see TV shows like Bachelor in Paradise and Jersey Shore: Family Vacation. But while the whole Kardashian clan took the stage to accept the award, Khloé didn't realize she had also won a separate award for Best Reality Star — because come on, she deserves at least two separate trophies for her work on the 17th season of the reality series.

On Twitter, Khloé apologized to fans for not acknowledging the second award on stage, revealing that she hadn't even realized she won it. Don't worry, Khloé: Most of us didn't know the People's Choice Awards were happening either. Read more at People. Scott Meslow

What to do when a pop star takes a show that was scheduled for 8:30 p.m. and pushes it back to 10:30 p.m.? You could chug an extra thermos of coffee, or sleep in so you'll have extra energy later in the day, or you could sue the singer for this incredibly trivial inconvenience.

That's the strategy being pursued by one Florida man, who filed a lawsuit against Madonna alleging that her decision to push back a December concert by two hours constituted a breach of contract. The lawsuit adds that the time change decreased the value of the $1,024.95 he spent on tickets — but come on, at least 40 percent of that is probably Ticketmaster fees. Read more at Page Six.
