As President Trump's "West Wing careens through one of the most turbulent weeks of his presidency, White House officials are struggling to understand the source of the fury fueling the president's eruptions," Vanity Fair reported Wednesday, quoting a former West Wing staffer: "This is a level of insanity I've never seen before." But Trump's "oddly detailed condemnation" of Special Counsel Robert Mueller on Twitter Thursday bolsters the speculation that Trump's mood is tied to the Russia investigation, Politico reports.

"Half a dozen people in contact with the White House and other Trump officials say a deep anxiety has started to set in that Mueller is about to pounce after his self-imposed quiet period, and that any number of Trump's allies and family members may soon be staring down the barrel of an indictment," Politico says. Trump and his lawyers have been meeting this week to answer Mueller's questions about Russia's Trump-friendly interference in the 2016 election. But Trump's "unusually specific" accusations against Mueller suggest the cause of his anxiety is based on specific knowledge, Natasha Bertrand reports at The Atlantic.

Trump's angry tweets "could just be another rant," former Manhattan federal prosecutor Elie Honig tells Bertrand. But Trump allies may also have informed Trump that Mueller's prosecutors are getting impatient with a less-than-forthcoming witness. "My hunch is that prosecutors had some sort of 'Time to get real' conversation with someone implicated in the investigation, which was then relayed to Trump by defense attorneys," Honig said. Fellow former federal prosecutor Dan Goldman agreed, saying he believes "indictments are coming," maybe Friday.

"You can see it in Trump's body language all week long, there's something troubling him," a senior Republican official in touch with the White House speculates to Politico. "It led me to believe the walls are closing in and they've been notified by counsel of some actions about to happen. Folks are preparing for the worst." Peter Weber

The Supreme Court on Monday announced it has accepted three cases involving gay and transgender employees, and will deliver rulings on whether federal anti-discrimination laws prohibit employers from firing workers due to their sexual orientation and gender identity.

The cases — Bostock v. Clayton County, Georgia; Altitude Express, Inc. v. Zarda; and R.G. & G.R. Harris Funeral Homes v. EEOC — will be decided during the court's term that will start in October. The justices will be tasked with deciding whether the protections granted by Title VII of the Civil Rights Act of 1964, which forbids discrimination on the basis of race, religion, national origin, and sex, also applies to people based on their gender identity or sexual orientation.

Bostock v. Clayton County, Georgia and Altitude Express, Inc. v. Zarda will be consolidated, as both involve employees who say they were fired for being gay. R.G. & G.R. Harris Funeral Homes v. EEOC involves a transgender woman who was fired from a Michigan funeral home because of her gender identity. In Altitude Express, Inc. v. Zarda and R.G. & G.R. Harris Funeral Homes v. EEOC, lower courts sided with the plaintiffs, NPR reports, but in Bostock v. Clayton County, Georgia, it was decided that Gerald Bostock was not fired from his job as a child welfare service coordinator because he is gay. Catherine Garcia

The leader of a New Mexico militia arrested on Saturday allegedly boasted that his organization, the United Constitutional Patriots, trained to assassinate former President Barack Obama, Hillary Clinton, and George Soros, a complaint filed over the weekend states.

Larry Mitchell Hopkins, 69, was arrested on suspicion of being a felon in possession of a firearm and ammunition. He is described as being the "commander" of the 20-member United Constitutional Patriots, a group that has been detaining migrant families crossing the southern border.

In the complaint, an FBI agent writes that someone called the agency's public tip line in October 2017, and said there was "alleged militia extremist activity" taking place in Hopkins' Flora Vista, New Mexico, home. This person also said Hopkins "allegedly made the statement that the United Constitutional Patriots were training to assassinate George Soros, Hillary Clinton, and Barack Obama," claiming that they were supporting anti-fascist activists. Hopkins' attorney denies his client said this.

FBI agents visited Hopkins' house in November 2017, and saw 10 firearms. Hopkins showed them several other weapons, and said they belonged to his common law wife, Fay Sanders Murphy, the affidavit says. After this visit, FBI agents found out Hopkins had prior felony convictions, including being found guilty in 2006 of criminal impersonation of a peace officer. Hopkins remains in custody, pending a preliminary hearing April 29 in Albuquerque. Catherine Garcia

The House Judiciary Committee issued a subpoena to former White House Counsel Don McGahn on Monday, requesting he testify in front of the panel on May 21.

Committee Chair Jerrold Nadler (D-N.Y.) said in a statement that Special Counsel Robert Mueller's report "outlines substantial evidence that President Trump engaged in obstruction and other abuses," and it's now up to Congress to "determine for itself the full scope of the misconduct and to decide what steps to take in the exercise of our duties of oversight, legislation, and constitutional accountability." McGahn, who spent 30 hours being interviewed by Mueller's team, was "a critical witness to many of the alleged instances of obstruction of justice and other misconduct described in the Mueller report," Nadler said, and his testimony "will help shed further light" on Trump's "attacks on the rule of law, and his attempts to cover up those actions by lying to the American people and requesting others do the same."

The subpoena also gives McGahn until May 7 to hand over documents related to ex-National Security Adviser Michael Flynn discussing sanctions with former Russian Ambassador Sergey Kislyak; Trump's firing of former FBI Director James Comey; and possible pardons for Flynn, Trump's ex-lawyer Michael Cohen, and Trump's former campaign chairman Paul Manafort.

Herman Cain here.

Those rumors about why the 2012 GOP presidential candidate dropped out of the running to be President Trump's next Federal Reserve Board nominee? They're not true, and Cain is the "only source you need" to get the real story, he writes in an op-ed for the conservative Western Journal published Monday.

While Cain hadn't even been nominated for a Fed spot, Trump tweeted Monday that his "friend Herman Cain" had "asked me not to nominate him for a seat." It seemed reasonable, seeing as enough Senate Republicans had already said they'd vote against Cain to doom his nomination. There's also the fact that sexual misconduct allegations forced Cain out of the 2012 presidential race, though he has denied those allegations.

But amid these reasonable explanations surrounding Cain's withdrawal, Cain wants to assure you that "Twitter wasn't inside my mind over the course of the past weekend," he wrote in his op-ed. Cain was more worried about divesting from his business interests, cutting his radio show and Fox Business appearances, and taking sizable pay cut in the process, he said.

Of course, Cain "did like the idea of serving on the Fed," he enthusiastically continued. Yet he wondered if he'd "be giving up too much influence to get a little bit of policy impact," Cain wrote — he reaches "close to 4 million people a month" with his "current media activities," after all. And after thinking, praying, and even drafting a now-discarded op-ed about why he wanted to continue pursuing the nomination, Cain ultimately decided to withdraw.

Sri Lanka's military now has "sweeping" new powers following a series of bombings on Sunday that targeted luxury hotels and churches during Easter services, killing almost 300 people, The Associated Press reports. Officials are blaming a radical Islamist group for the attacks.

Sri Lanka's president, Maithripala Sirisena, granted the military a wider berth to arrest and detain suspects, per AP. The powers were reportedly in place during Sri Lanka's 25-year civil war, but were stripped away after the conflicted ended 10 years ago.

The decision is in line with the government's choice to enact a curfew and block some social media sites, including Facebook, WhatsApp, and Instagram, though the latter reportedly did little to "reassure residents and visitors that the danger had passed."

Prime Minister Ranil Wickremesinghe said he would "vest all necessary powers with the defense forces" to prevent instability and act against those responsible.

A nationwide state of emergency began on Tuesday, along with a national day of mourning. Read more at The Associated Press. Tim O'Donnell

An alarming number of young e-cigarette users don't realize just how much nicotine they're exposed to when vaping, a new study has shown.

Published on Monday in the journal Pediatrics, new research revealed that adolescents were getting a high amount of nicotine even when they thought the products they were using were nicotine-free. The study surveyed more than 500 adolescents, and then performed urine tests on 284 of those, and eventually found that about 40 percent of teens who thought they were using nicotine-free products still tested positive.

While e-cigarettes are thought by some to be healthier than traditional cigarettes, nicotine is no less addictive in a Juul than in a Marlboro. And in many cases, vapers were found to be taking in similar levels of nicotine in their e-cigarettes compared to traditional cigarettes.

The addictive powers of nicotine are causing concern that the lack of awareness around e-cigarettes may lead to a "generation of addicted young people" who will vape for years to come, or even switch to more harmful traditional cigarettes, NBC News reported. "This may be a pathway into nicotine addiction" that nobody saw coming, explained Andrew Stokes, a professor of global health at Boston University.
