Tens of thousands of protesters marched in 900 cities across the United States on Thursday night, showing their support for Special Counsel Robert Mueller.

In New York City, more than 6,000 people marched from Times Square to Union Square, holding signs that said "Nobody is above the law" and chanting "Hands off Mueller!" Organizers quickly mobilized after the forced resignation of Attorney General Jeff Sessions on Wednesday, saying on the Nobody is Above the Law website: "Donald Trump has installed a crony to oversee the special counsel's Trump-Russia investigation, crossing a red line set to protect the investigation. Our hundreds of response events are being launched to demonstrate the public demand for action to correct this injustice."

President Trump named Sessions' chief of staff, Matthew Whitaker, as the acting attorney general, and he will now oversee the Mueller probe, taking over for Deputy Attorney General Rod Rosenstein. Whitaker has said he believes the Department of Justice should withhold funding from the special counsel and questioned its scope. Catherine Garcia

The Pentagon is finalizing a policy to closely examine recruits who have green cards or other foreign ties, an initiative that would likely target thousands of people every year, two Department of Defense officials with knowledge of the matter told The Washington Post.

Last year, a federal judge blocked a similar effort to target green-card holders. The Pentagon is concerned about espionage and terrorism, and this new vetting process will screen "foreign nexus" risks, the Post reports; this could include people with foreign citizenship and those with family members who are not U.S. citizens.

Some U.S. citizens could also be targeted, including those with foreign spouses or relatives with dual citizenship. Anyone chosen for this screening would not be allowed to go to recruit training until they are cleared, which could take days for some and much longer for others. Defense Department officials told the Post the new policy will be distributed to military services no later than Feb. 15. Catherine Garcia

A 27-year-old Marine veteran with PTSD was held for three days in an Immigration and Customs Enforcement detention center in Michigan, despite being born in the United States, his lawyers said Wednesday.

Jilmar Ramos-Gomez pleaded guilty last month to trespassing and damaging a fire alarm at a hospital in Grand Rapids, the ACLU said. He spent some time in a Kent County jail, and was set for release on Dec. 14 to await sentencing. ICE contacted the jail and asked that Ramos-Gomez be held for pickup, and he was then driven 70 miles to Battle Creek. He was there for three days before a lawyer working for his family called the ICE detention center and told authorities Ramos-Gomez is a citizen.

In an interview with NBC News, ACLU attorney Miriam Aukerman asked why ICE, which has access to fingerprint records, thought Ramos-Gomez should be deported. "Why did they think he was a non-citizen? Did they get him confused with someone else? Who knows. This is an individual who's incredibly vulnerable with a mental illness." Ramos-Gomez was a lance corporal in the Marines, and earned awards for service in Afghanistan. He is now receiving mental health care for his PTSD.

The ACLU is calling on the Kent County sheriff and county commissioners to look into why the jail released Ramos-Gomez to ICE. Kent County Undersheriff Chuck DeWitt told NBC News that once Ramos-Gomez "was released from our custody, he was under the domain of ICE. Where they take him is their process. Our procedures were followed." Catherine Garcia

Federal workers will get a paycheck at some point.

President Trump signed a bill Wednesday that ensures federal employees furloughed during the partial government shutdown will get back pay once it's over. Trump has long shown support for the bill, which was introduced by Virginia Democratic Sens. Tim Kaine and Mark Warner last week and easily passed both houses of Congress.

Federal employees working without pay throughout the shutdown were already guaranteed back pay once the government reopened. This new law grants back pay to those furloughed during the shutdown. But it doesn't guarantee a paycheck for federal contractors, something Warner pushed for in a Wednesday tweet. He also, of course, advocated for the government to reopen after its 25-day-long shutdown. Kathryn Krawczyk

Rep. Ed Case (D-Hawaii) barely made it two weeks into his term before stirring up some controversy.

The congressman, who is fully aware that he's white, described himself as "an Asian trapped in a white body" at an event Tuesday, per National Journal fellow Nicholas Wu. And, as The Washington Post astutely said, "his apology didn't help" his case.

Case was at "an event celebrating Asian-American and Pacific Islander advances in Congress," Hawaii News Now says, but it's unclear what led up to the comments. What is clear is that Case represents America's only majority-Asian district.

Case told Hawaii News Now that he is "fiercely proud" of representing a state "where no ethnic group has been in the majority for generations." He added that he has "absorbed and live the values of our many cultures" and he "regret[s] if my specific remarks to the national API community on my full absorption of their concerns caused any offense." Also of questionable note: Case's spokesperson said the congressman was just repeating "what his Japanese-American wife sometimes says about him," per the Post.

Case first graced the House in Hawaii's 2nd District from 2002-2007, before leaving the post for an unsuccessful Senate run. He ran for the Senate again in 2012, losing to then-Rep. Mazie Hirono (D-Hawaii) in 2012. This time around, he won a primary of largely minority candidates to win his seat. Kathryn Krawczyk

Senate Majority Leader Mitch McConnell (R-Ky.) may be the only thing standing between a spending bill and the president.

House Democrats and a few Republicans passed two spending bills last week that would reopen the government, but McConnell refused to bring them before the Republican-held Senate. And on Tuesday, McConnell did it again — even though Democrats "have secured enough Republican votes in the Senate to reopen government," Rep. Alexandria Ocasio-Cortez (D-N.Y.) tweeted Wednesday.

The government shutdown began Dec. 21 over President Trump's refusal to sign a spending bill without $5.7 billion in border wall funding. Democrats still refuse to bend to that demand. And when they took over the House this year, they and five Republicans quickly passed a spending bill to fund most government departments for the year and another that would fund the Department of Homeland Security for 30 days. McConnell refused to bring them for a vote in the Senate, saying they were "absolutely pointless show votes" on bills Trump wouldn't sign.

Democrats pointed out that the GOP-held Senate passed similar bills last year, which then-House Speaker Paul Ryan (R-Wisc.) wouldn't bring for a vote. And when those House Democrats, along with 12 Republicans, voted Friday to send a new set of spending bills to the Senate, McConnell again turned them down. Kathryn Krawczyk

The creators of the massively popular online game Fortnite have acknowledged a security flaw that may have put players' accounts at risk.

Check Point Research said Wednesday they discovered a bug that would allow hackers to obtain users' login username and password if they clicked on a phishing link; the user would not need to enter any information at this link for their account to be taken over by the hacker, they say. The group blames this on a "vulnerability found in some of Epic Games' sub-domains."

Epic Games, the company behind Fortnite, says that the security bug has been fixed, though it did not disclose how many users were affected. "We thank Check Point for bringing this to our attention," the company said, per Fortune.

Since Fortnite thrives off in-game currency, once a hacker had logged in to a victim's account, they would be able to make purchases using the person's credit card information, The Washington Post notes. Check Point Research also points out that hackers could have been able to listen into private chats by impersonating the user they hacked, although Epic Games clarified to The Verge that the hackers wouldn't be able to eavesdrop on the person whose account they'd taken over.

Fortnite has more than 200 million users and, according to The Verge, generated an estimated $2.4 billion in 2018. Brendan Morrow
