With less than three hours to go until the majority of the polls in Texas close, Beyoncé slipped in a very, very last-minute endorsement of Rep. Beto O'Rourke, the Democrat challenging GOP Sen. Ted Cruz for his seat. "We can't voice our frustrations and complain about what's wrong without voting and exercising our power to make it right," she wrote in her Instagram post, even though more than 4.5 million people have already cast early voting ballots in the Lone Star State.

"This would normally be a massive boost to a candidate in Texas," wrote The Texas Tribune's political editor, Aman Batheja, on Twitter, adding: "Genuinely curious: Are there registered voters whose behavior will be influenced by such a late endorsement?"

Many other celebrities offered more timely endorsements of O'Rourke, including LeBron James, Jim Carrey, and Eva Longoria. But better, uh, late than never? Jeva Lange

Special Counsel Robert Mueller's report is here, and pretty much no one knows what's in it.

The Justice Department announced Friday that Mueller had finished his investigation into potential ties between President Trump's campaign and Russian election interference. And within minutes, even the most unexpected lawmakers started calling for Attorney General William Barr to release it to the public.

First up came a wave of Democratic voices. House Speaker Nancy Pelosi (D-Calif.) and Senate Minority Leader Chuck Schumer (D-N.Y.) issued a joint call for public report, while 2020 candidates chimed in with some variation on the theme. Sen. Chuck Grassley (R-Iowa) also surprisingly called for a public release, saying it was needed to "put an end to the speculation and innuendo that has loomed over the administration."

Those calls reflected a 420-0 House vote last week on a non-binding resolution to make the report public. Heck, even Trump said Tuesday that he wouldn't mind if Congress saw what Mueller had to say. But there's still one major holdout: Senate Judiciary Committee Chair Lindsey Graham (R-S.C.). In his Friday statement, Graham reflected Barr's language in simply calling for "as much transparency as possible, consistent with the law." Graham also blocked the House's popular resolution from a vote in the Senate earlier this week.

Grassley did pointedly note Friday that he was in Graham's committee position just last year — perhaps something he's regretting giving up right about now. Kathryn Krawczyk

A senior Justice Department official said Friday that Special Counsel Robert Mueller will not recommend any further indictments, ABC News reports.

Mueller, whose inquiry into collusion between the Trump campaign and Russian election interference was completed late Friday afternoon, had issued indictments for more than three dozen individuals over the nearly two-year investigation, including for former Trump campaign chair Paul Manafort and former National Security Adviser Michael Flynn.

While the lack of new indictments may come as a disappointment to those who saw Mueller's report as a potentially crippling blow to the Trump administration, it is still unclear what the completed report contains — and NBC News notes that evidence uncovered by the special counsel's probe could be used in other investigations, like in the Southern District of New York. But the spectacle of former Trump associates being led into court as a result of Mueller's investigation appears to have come to an end. Jacob Lambert

Although Special Counsel Robert Mueller missed his chance to deliver his report to Attorney General William Barr on the Ides of March, he picked another significant date to finish the long-awaited conclusion.

On March 22, 1973, a conversation between former President Richard Nixon and his former attorney general, John Mitchell, was recorded — a conversation that was later used to indict Mitchell on charges of conspiracy, obstruction of justice, and perjury for his role in the attempted cover-up of the Watergate scandal of 1972. In this recording, Nixon can be heard instructing Mitchell to "stonewall" the ongoing Watergate trial and "save the plan."

Comparisons between Presidents Nixon and Trump have been endlessly drawn since Trump assumed office in 2017, which makes this historical coincidence particularly noticeable. But we won't know if a conspiracy on the scale of Nixon's has occurred in the Trump White House unless the conclusions of Mueller report are made public — which could happen as soon as this weekend.

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."

Saying goodbye is never an easy task. But with streaming services like Netflix and Hulu, is it really goodbye? Amari Pollard
