Earlier this month, Jonathan Wienke, an analyst in the Department of Homeland Security’s Office of Intelligence and Analysis, was arrested after carrying a gun, a knife, an infrared camera, pepper spray, and handcuffs into the agency’s headquarters. Now, court filings show, federal prosecutors are investigating whether Wienke was planning an attack on senior DHS officials.

According to a letter released by the Senate Homeland Security Committee, Omar Mateen checked his phone to see whether “Pulse Orlando” and “shooting” had begun trending on Facebook after he took hostages during his deadly rampage at the gay nightclub on Sunday.

On Thursday, the Department of Homeland Security announced that 41 Secret Service employees have been disciplined in connection with a leak intended to embarrass the Republican congressman tasked with overseeing the agency.

Following accusations of departmental mismanagement, Kelly Hoggan, the Transportation Security Administration’s head of security, was removed from his position on Monday, CNN reports.

Speaking to CBS This Morning, former Homeland Security secretary Michael Chertoff suggested that the U.S. ought to respond to today’s horrific attacks in Brussels with a useless and silly measure that will make absolutely no one safer.

It's a cliche: the frighteningly out-of-touch congressman, too old and removed from the world to form legislation that could help it. But it's also real life, and watching Rep. John Carter of Texas try to grapple with computer security is funny until it's scary and sad.

A new Homeland Security report cites nearly a dozen "factors" that allowed intruder Omar Jose Gonzalez to break into the White House this September, ranging from malfunctioning radios to a mistaken belief by Secret Service agents that White House bushes "were an impassable barrier."

A TSA employee living near Sacramento, Calif. is facing underage sex charges after FBI agents posing as a woman and her teenage daughter caught him in a Craigslist sting.

Good news: Uncle Sam's terrorist-watchin' lawmen would like a database that shows the whereabouts of every car with a license plate that's recently been scanned by a government tag reader. Does that freak you out? Here's better news: They want a private contractor to run it.

Ayo Kimathi works as a small business specialist for the Department of Homeland Security. After work, he reportedly runs a website called War on the Horizon, which features your standard federal employee opinions, like describing President Obama as "a treasonous mulatto scum dweller … who will fight against reparations for Black people in amerikkka, but in favor of fag rights for freaks in amerikkka and Afrika."

An unnamed FBI official has told CBS News that at least one of the explosive devices detonated in Boston yesterday appears to have been improvised from a conventional pressure-cooker. Unnamed law enforcement officials don't exactly have the strongest record of credibility in the immediate aftermath of events like these, but federal authorities are well-acquainted with this type of IED.

Here's a good tip for foreign travelers hoping to visit the United States: no matter what the words "destroy America" might mean among your hometown folk, you may want to keep that phrase off your Twitter feed. Emily Bunting and Leigh Van Bryan, a pair of tourists from Great Britain, found this out the hard way after they were detained by Homeland Security for twelve hours at Los Angeles International Airport because Bryan had earlier tweeted "Free this week, for quick gossip/prep before I go and destroy America." Bryan tried in vain to explain that "destroy" is just a quirky Brit way of saying "going out and getting drunk," but the humorless DHS agents presumably had not heard of partying, either. So they were deported.

It's been a while since we last heard about a loaded gun slipping past the watchful eyes and groping, toy-taking hands of TSA's diaper-busting agents and making it onto an airplane. We thought that maybe the agency had patched up that minor security breach issue, or something. Nope!

Remember the various reports of "suspicious activity" on planes on the anniversary of 9/11? Here's the story of one of the people who was detained—apparently for being half-Arab and sitting next to two Indian men who got up to use the bathroom in succession. Very suspicious!

Officials "are very concerned" about new information regarding a planned terror strike on the tenth anniversary of 9/11, CBS News reports, with the plot potentially targeting either New York City or Washington, D.C. The threat is "specific and credible but unconfirmed." Great. What does that mean?

It's a TSA metal detector party, and your ugly footwear will soon be invited. Homeland Security Secretary Janet Napolitano tells Politico's Mike Allen that air travelers will soon be permitted to keep their shoes on during security checks:

Remember the government's color-coded terror alert system? Sure you do. It was fun, festive, and went with everything. Well, it's history. Back in January, the Department of Homeland Security announced plans to phase out the system. So what will replace it? As of April 27, terror alerts will come in just two forms —"elevated" and "imminent"— and will be broadcast over the two most popular social networks.

"In some ways," the threat of terrorism is "at its most heightened state" since 9/11, Homeland Security Secretary Janet Napolitano told the House Homeland Security Committee on Wednesday. Certainly, the threat of magazine-publishing is at a very heightened state—perhaps its most heightened state—as National Counterterrorism Center Michael E. Leiter testified regarding the "spiffy" magazine from al Qaeda in the Arabian Peninsula, Inspire. ("It's got great graphics," he told committee members, which is more than we can say for the Tea Party Review.)

According to a new report, less than one percent of the U.S.-Canada border has an "acceptable level" of security. Mounties could be invading as we speak! Do you want your children listening to the Tragically Hip? Build a wall now!

George W. Bush's greatest gift to this country, the color-coded terrorist warning system, is going away forever. The government is starting to phase it out this week. For now, let's look back at this system's one great contribution to society.
