Police have identified the suspected gunman who opened fire and killed at least 12 people at a California bar as 28-year-old Ian David Long, a veteran of the Marine Corps.

The shooter entered the Borderline Bar & Grill in Thousand Oaks, California, at about 11:20 p.m. Wednesday night, Ventura County Sheriff Geoff Dean said early Thursday, per The Associated Press. A sheriff's sergeant who was responding at the scene, Ron Helus, was among those killed. Authorities said Thursday that the gunman used a .45-caliber handgun, which he purchased legally and modified.

Authorities also said Thursday that police had had a number of interactions with the suspect over the years for "minor events," such as a traffic collision. In April, deputies were called to his house, and he was "acting a little irrationally," Dean said. A crisis intervention team was called out and a mental health specialist cleared him.

The suspect was found dead in the bar, the county sheriff said, and authorities believe he shot himself. Witnesses to the shooting had said that he was dressed in all black and wearing glasses, CNN reports. Records show the suspected shooter served in the Marine Corps from 2008 to 2013. Brendan Morrow

President Trump and his defenders have latched onto the fact that two FBI employees involved in the bureau's investigation into 2016 Russian election interference — agent Peter Strzok and lawyer Lisa Page — exchanged text messages criticizing Trump while the probe was ongoing. But Justice Department Inspector General Michael Horowitz may have poked a hole in that argument during his testimony before the Senate Judiciary Committee hearing Wednesday.

Horowitz discovered quite a few things wrong with the investigation, but his team concluded that political bias didn't hinder their efforts, which he reiterated while testifying. He also confirmed that other FBI employees were also discovered to have sent politically-charged text messages. And at least some of those conversations were supportive of Trump.

So, while it's clear individual agents were harboring specific sentiments about the commander-in-chief, things apparently didn't go down exactly the way Trump thought. Tim O'Donnell

Pete Buttigieg has some very presidential explaining to do.

As the South Bend, Indiana, mayor and 2020 Democrat began talking about his consulting work with McKinsey Co., former health insurance executive turned Medicare-for-all advocate Wendell Potter suspected Buttigieg worked with a client that would be "very significant in this campaign." And when Buttigieg's client list came out, Potter's hunch proved true: Buttigieg had worked with Blue Cross Blue Shield of Michigan just before it hiked its insurance premiums and axed nearly 1,000 employees.

Potter first shared his theory in a Monday Twitter thread, saying the health insurance company he'd previously worked for "had McKinsey on retainer," and that the consulting firm was brought in "when one division or another wasn't making enough profit." Buttigieg described his work for BCBS as "identifying savings in administration and overhead costs," which to Potter are "code words" meaning "cutting costs through layoffs, restructuring, and potentially denying health coverage." Buttigieg spent three months with the health insurance provider in 2007 — a year BCBS reported a 27 percent drop in net earnings. That exact loss was mentioned by BCBS exectuives when, two years later, the provider announced layoffs of up to 1,000 workers and double-digit premium increases.

Buttigieg's mysterious work for McKinsey had been a subject of criticism throughout his campaign, especially after a New York Times report showed McKinsey's work with U.S. Immigrations and Customs Enforcement led to severe cuts in detainee care. Buttigieg said he wasn't able to release the details of his work until Tuesday. Kathryn Krawczyk

Robert De Niro has once again been snubbed at a key Oscars precursor, putting his chances of a best actor win in doubt.

The nominations for the 2020 Screen Actors Guild Awards were announced Wednesday, and in the lead actor category, De Niro was surprisingly not nominated for his performance in The Irishman. That's not a great sign considering the winner of the best actor award at the Oscars is almost always at least nominated in this equivalent category the SAG awards.

Instead, the nominees for the SAG best actor prize this year are Christian Bale for Ford v Ferrari, Leonardo DiCaprio for Once Upon a Time in Hollywood, Adam Driver for Marriage Story, Taron Egerton for Rocketman, and Joaquin Phoenix for Joker. DiCaprio, Driver, and Phoenix were all widely expected to get nominations, though Egerton's nod for some came as a surprise.

De Niro will be honored by SAG with a Life Achievement Award this year, however, and The Irishman itself earned a nomination for best cast, so Gold Derby wonders if "perhaps voters thought he'd be duly rewarded there."

Still, this snub comes after De Niro was also conspicuously left out in the cold at the Golden Globe Awards, where Bale, DiCaprio, Driver, Egerton, and Phoenix all received nominations, although in separate fields since the Golden Globes divides its awards into drama and musical or comedy categories.

De Niro isn't the only actor whose Oscars prospects are looking worse this week than last, with Uncut Gems' Adam Sandler also getting snubbed at both the Golden Globes and the SAG Awards, while Dolemite Is My Name's Eddie Murphy got nominated at the Golden Globes but missed at the SAG Awards.

After these two snubs, when it comes to picking up an Oscar nomination let alone a win, The Washington Post's Thomas Floyd observes it seems De Niro now "faces an uphill climb." Brendan Morrow

Senate Judiciary Committee Chair Lindsey Graham (R-S.C.) just spent more than 40 minutes tearing into the FBI for its handling of the 2016 investigation into Russian election interference.

In his opening statement before Justice Department Inspector General Michael Horowitz's testimony before the Senate panel on his report on the probe, Graham said FBI agents were "biased" against President Trump and questioned whether the agency had selected its top individuals. Graham did say he respects the FBI as a whole, but is still troubled by Horowitz's report.

Several observers noted that during his oration, Graham didn't mention that Horowitz — despite finding several issues with the probe — also concluded that it was justified and free from political bias when launched.

Graham also surprised a few people when he mused over whether the United States Foreign Intelligence Surveillance Court should continue unless it's reformed. That's because he's been an ardent supporter in the past. Tim O'Donnell

U.K. Prime Minister Boris Johnson is giving the media the cold shoulder.

Johnson made an early-morning visit to a dairy business in England on Wednesday when a producer for Good Morning Britain, hosted by Piers Morgan and Susanna Reid, walked up and asked if he'd go live with the show. "I'll be with you in just a minute," Johnson said, before turning and walking into a giant fridge full of milk.

Jonathan Swain, the Good Morning Britain producer, made several attempts to get Johnson on the air. His first one was rebuffed by Johnson's press secretary, who can be seen mumbling an expletive. Swain then continues trying to milk Johnson for an interview, asking him to "deliver on your promise to talk to Piers and Susanna" and telling him he has an earpiece ready. But Johnson stays glued to his tour, lifts some milk crates, and eventually escapes into the fridge. Watch the whole chilling scene below. Kathryn Krawczyk

The sanctions keep on coming.

The U.S. Treasury Department's Office of Foreign Assets Control on Wednesday announced sanctions on Iran's largest shipping company and airline in an attempt to stop the development and proliferation of weapons of mass destruction, the Financial Times reports.

The shipping company, the Islamic Republican of Iran Shipping Lines, has been accused of smuggling weapons into Yemen on behalf the Islamic Revolutionary Guard Corps; OFAC said the U.S. seized weapons on a small boat last month believed to be on their way to Houthi rebels. OFAC also said Mahan Air has aided the IRGC and has also "moved weapons and personnel for Hezbollah" and the Assad regime in Syria.

Secretary of State Mike Pompeo said the U.S. will continue a maximum pressure campaign of sanctions against Iran. Tim O'Donnell
