They say a man can be known by the company he keeps, and Donald Trump kept — and then turned his back on — one of America's most notorious figures. For 13 years, Trump looked up to his "closest friend" and mentor Roy Cohn, who in the 1950s shadowed Sen. Joe McCarthy as the legal aide behind the Red Scare and the infamous communist hearings, Politico reports.

"[Cohn] became Donald's mentor, his constant adviser on every significant aspect of his business and personal life," Village Voice investigative journalist Wayne Barrett said.

As Trump's lawyer, Cohn advised the real estate mogul on everything from getting a prenuptial agreement before his marriage to first wife Ivana to helping negotiate a $20 million tax abatement for the construction of Trump Tower. But it wasn't just business — the two were genuinely buddies:

In The New York Times in 1980, Cohn called himself "not only Donald's lawyer, but also one of his close friends."

They talked, according to Vanity Fair, "15 to 20 times a day."

Trump even stuck with Cohn through his disbarment proceedings, when Cohn was hit with charges of fraud, deceit, and misrepresentation. And while Cohn was indeed disbarred in the end, it wasn't until Trump learned that Cohn had been diagnosed with AIDS that he decided to sever his ties with his mentor.

"Donald found out about it and just dropped him like a hot potato," Cohn's longtime secretary Susan Bell said. "It was like night and day."

Cohn was reportedly stunned by the betrayal, after all he'd done for Trump. "Donald pisses ice water," he is quoted as saying in Barrett's 1992 book about Trump.

The company a man keeps is one thing — but perhaps a whole other is why he leaves in the end. Read the full story in Politico. Jeva Lange

News that Special Counsel Robert Mueller had submitted his final report to the Justice Department on Friday fueled speculation that President Trump could be in for a very rough weekend, but several pundits weren't so sure.

While Rep. Eric Swalwell (D-Calif.) warned that the Democratic-controlled House has "subpoena power" and promised "the American people will see every word, every comma, every period" of the report on whether the Trump campaign was involved with Russian election interference, but CNN analyst Jeffrey Toobin thought eager viewers should cool their jets.

While Attorney General William Barr wrote that he could brief Congress on the report's conclusions "as soon as this weekend," Toobin said that if he does share the findings, "it's going to take a while," not come within days. Several agencies will have to weigh in on whether aspects of the report can be declassified, said Toobin, though he acknowledged the process was going quicker than he expected.

Toobin also asserted that Mueller was "never told no" during his investigation, something ABC News' Terry Moran agreed with, saying Mueller had "free reign" and still opted not to bring any more charges against Trump campaign officials. However, Moran said "it's possible that we will learn a conclusion, the broad conclusion, very quickly," suggesting no further indictments and a completed investigation will speak for themselves, forming a de facto "no collusion" conclusion.

The White House heard the news approximately 30 seconds before the rest of the world.

Right around 5 p.m. EST Friday, the Department of Justice announced Special Counsel Robert Mueller had finished his investigation into potential ties between President Trump's campaign and Russian election interference. The White House reportedly heard the news only a few minutes before the announcement — and this reaction from President Trump's lawyer Rudy Giuliani seems to prove it.

As speculation mounted throughout the day that Mueller had finished his report, Giuliani delightfully told The Washington Post that all this hype was "like waiting for a baby." He also added that Trump's team was "not expecting" further indictments from the report. Yet as the first report surfaced confirming the rumors were true, Giuliani appeared shocked, telling The Hill "I can't believe they'd put out a report at 5 o'clock on a Friday — but they've surprised me before." He and fellow Trump lawyer Jay Sekulow then issued a full statement.

The White House also followed up the news with a statement of its own, confirming that the White House did not get to look at Mueller's report before its completion.

Meanwhile, officials who've talked with Trump tell ABC News that he's just "glad it's over." Kathryn Krawczyk

We knew this day would come.

Supernatural stars Jensen Ackles, Jared Padalecki, and Misha Collins announced on Friday via Instagram that the show will come to an end after its 15th season. From their red eyes, it was clear the three actors had been crying over the news — which they had just broken to the crew before taking to social media.

"Well, it's official. One more round for the Winchester brothers," Padalecki wrote in his instagram caption. "Though nothing ever really ends in Supernatural ... does it?"

The series is currently in its 14th season and recently celebrated its 300th episode in November, reports E! News. Supernatural was renewed for a 15th season at the beginning of the year with no hint of the show ending soon, but after 20 episodes in the next season, it'll all be over.

"For us it has been an experience of a lifetime," said executive producers Robert Singer and Andrew Dabb in a joint statement. "It is now most important to us to give these characters that we love the send off they deserve."

Special Counsel Robert Mueller has finished his report, but hardly anyone knows what's in it.

The Department of Justice announced Friday afternoon that Mueller had finished his investigation into potential ties between President Trump's campaign and Russian election interference. Attorney General William Barr similarly told the House and Senate Judiciary committees he had received the report Friday — and said he might tell them what's in it "as soon as this weekend."

In a letter to the committees on Friday, Barr said that Mueller faced "no such instances" where he was blocked from taking an action he wanted to pursue. There had been concerns that President Trump would not submit to in-person questioning by Mueller, but if this was something Mueller attempted, it was seemingly not blocked.

"Only a few people" have seen the report so far, a Department of Justice official told CNN's Shimon Prokupecz after its conclusion. Barr has refused to commit to releasing the whole report to the public or even to Congress, but he said in his Friday letter that he may have Mueller's "principle conclusions" ready for the judiciary committee "as soon as this weekend." Barr continued to say that he would "consult with" Mueller and Deputy Attorney General Rod Rosenstein "to determine what other information can be released to Congress and the public," and added that he "remain[s] committed to as much transparency as possible."

Special Counsel Robert Mueller's report is done.

Mueller finished his investigation into potential ties between President Trump's campaign and Russian election interference, the Justice Department said on Friday. The confidential report was delivered to Attorney General William Barr, who has said he will provide a condensed version of the report to Congress. He has not committed to releasing the full report to Congress or the public.

The Washington Post's Ellen Nakashima first reported that the House Judiciary Committee was told to expect notification by 5 p.m. Friday that Mueller had finished the report. Reports had surged in the last few weeks that Mueller was wrapping up his report, and reporters staking out his office chalked up several reasons to predict it would wrap Friday. Kathryn Krawczyk

The mayor of San Juan who outspokenly criticized the Trump administration's response to a hurricane-ravaged Puerto Rico announced she will run for governor in 2020.

Mayor Carmen Yulín Cruz announced her bid on Friday, telling an audience in Puerto Rico it is time to "break away from the chains that tie us down in order to have a promising future and break our cycle of poverty," reports NBC News.

Cruz rose to national prominence after Hurricane Maria hit Puerto Rico in 2017. When President Trump called the response to the hurricane "incredible," Cruz responded by saying "Where have you been?" and lambasting the Trump administration's slow response to supplying emergency aid. Trump has criticized Cruz for being "nasty" and reflecting "poor" leadership.

She hasn't only criticized Trump, though — in her announcement, she also criticized current Gov. Ricardo Rosselló, who she said "was unable to count deaths after Hurricane Maria" and "stood by Trump when he threw paper towels at people."

Cruz is running as a member of the Popular Democratic Party, which opposes statehood for Puerto Rico, per NBC News. Marianne Dodson
