In a Monday night Facebook post, the Department of Homeland Security claimed it was necessary to fire tear gas at migrants who approached the southern border on Sunday.

DHS Secretary Kirstjen Nielsen said the "violence we saw at the border was entirely predictable," referring to reports that Central American migrants who reached the San Ysidro port of entry to apply for asylum in the U.S. had thrown rocks at law enforcement after becoming frustrated that they were not able to plead their cases. "Officers can be seriously or fatally injured in such attacks," said Nielsen, though no officials were injured during the incident. Border Patrol fired tear gas into Mexico "to dispel the group" and closed the port.

"It appears in some cases that the limited number of women and children in the caravan are being used by the organizers as 'human shields' when they confront law enforcement," claimed Nielsen. Images of children affected by tear gas provoked outrage, especially among Democrats who said the Trump administration's handling of the migrant caravan had gone too far.

President Trump also defended the gassing, telling reporters that Border Patrol agents "had to" use tear gas "because they were being rushed by some very tough people." He also said agents had only used a "very minor form" of tear gas, calling it "very safe" and claiming the children affected were only there because "grabbers" were pretending to be their parents to attain a "certain status."

Migrants were denied entry and remain in Mexico. Nielsen concluded her statement by saying the administration is continuing "to prepare for the next assault." Summer Meza

Last October, Sen. Chris Coons (D-Del.) sent FBI Director Christopher Wray a letter stating that he had relevant information regarding the allegations of sexual assault made against President Trump's Supreme Court nominee, Judge Brett Kavanaugh, but the FBI appears to have ignored him, The New York Times reports.

The Times obtained a copy of this letter, which states that Coons heard from multiple people who said they had information on Kavanaugh. He told Wray that he "cannot speak to the relevance or veracity of the information that many of these individuals seek to provide, and I have encouraged them to use the FBI tip portal or contact a regional FBI field office. However, there is one individual whom I would like to specifically refer to you for appropriate follow-up."

Coons was asking the FBI to contact one of Kavanaugh's former Yale classmates, Max Stier, Coons' spokesman Sean Coit confirmed. Over the weekend, the Times reported that during Kavanaugh's freshman year, Stier saw Kavanaugh with his pants down, and his friends pushed his penis into a female student's hand. Stier notified senators and the FBI about the incident, the Times says. The incident has similarities to an allegation made by a former classmate named Deborah Ramirez, who said Kavanaugh exposed himself to her during a party at Yale their freshman year.

Several Democratic presidential candidates have called for Kavanaugh's impeachment, while Sen. Richard Blumenthal (D-Ct.) on Monday said there should be a "full, fair investigation, as was never done at the time. It was a sham, as we said then, and there should be a full inquiry now."

British Prime Minister Boris Johnson was greeted by the sound of protesters booing him when he arrived in Luxembourg on Monday, and the reception he received from the country's top leaders wasn't much friendlier.

Johnson was in Luxembourg for his first face-to-face meeting with European Commission chief Jean-Claude Juncker, The Associated Press reports. With Britain scheduled to leave the European Union on Oct. 31, the two are trying to come up with a divorce agreement, but the European Commission said in a statement the meeting ended with no plan in place. Johnson has not offered any "legally operational" solutions to the so-called "backstop," which would guarantee that goods and people are able to freely cross the border between EU member Ireland and the U.K.'s Northern Ireland.

Johnson was scheduled to attend a news conference with Luxembourg Prime Minister Xavier Bettel, but refused to attend due to the rowdy anti-Brexit protesters. Bettel met with him privately, and said Johnson needs to "stop speaking and act," adding, "You can't hold their future hostage for party political gains." A no-deal Brexit could have catastrophic economic repercussions, but Johnson is adamant that Britain will leave the EU by Halloween, with or without a deal.

An EU summit will be held in mid-October, and hopes are high that a deal will be reached then. Johnson suspended Parliament until Oct. 14, in order to give himself distance from lawmakers who are trying to block a no-deal Brexit, and on Tuesday, Britain's Supreme Court will mull whether that decision was lawful.

Some Asian Americans laughed when entrepreneur Andrew Yang's said on the debate stage Thursday night in Houston that he knew a lot of doctors because he's Asian. But others find that that the presidential candidate's supposedly self-deprecating humor — which has also included jokes about being good at math and loving to work — too often reinforces racial stereotypes, The Washington Post reports.

"I found this part galling, because here he is sort of obtusely reinforcing the model-minority myth and model-minority stereotypes," Jenn Fang, who runs the blog Reappropriate, told the Post, referring to the debate line. Fang added that, in making a comment like that, Yang also "implicitly suggests that the Asian American experience is only represented by his specific middle-to-wealthy-upper-class East Asian American experience," which in the process "completely flattens all of the other ways people are Asian American and don't have access to health care and access to higher education."

Yang, though, has defended himself. In an interview with CNN's Jake Tapper over the weekend, the candidate said the "Asian American American community is very diverse, and certainly I would never claim that my individual experience would speak to the depth and breadth of our community." In fact, Yang argues, by "poking fun" at the myth surrounding Asian Americans, he's "making Americans reflect more on it."

Janelle Wong, a professor of Asian American studies at the University of Maryland, said it's "certainly dangerous" for Yang to "deploy stereotypes," but he is also "breaking stereotypes by seeking the presidential nomination." Read more at The Washington Post. Tim O'Donnell

John Bolton might be ready to drop a (thankfully metaphorical) bombshell.

President Trump fired/accepted the resignation of his national security adviser last Tuesday amid reports that Bolton was fighting with just about everyone in the White House. Bolton eerily left his position with a promise that he would "have my say in due course," and less than a week later, The Daily Beast is reporting that "due course" could be sooner than expected.

Bolton is already talking with literary agents in hopes of writing a memoir of his time working for Trump, two people with knowledge of the situation tell The Daily Beast. "He has a lot to dish," one of the sources said, though both what was on the menu and when it will be served have yet to be revealed. Bolton would join a long line of former Trumpers to give an inside scoop on their White House tenures, and judging by the rocky way Bolton went out, it wouldn't be the softball former Press Secretary Sean Spicer tossed out there.

When asked about a possible book deal, Bolton only told The Daily Beast he had "no comment." Read more at The Daily Beast. Kathryn Krawczyk

President Trump still doesn't want to go to war with Iran, he said, but the U.S. is prepared for it nonetheless.

Saudi Arabia announced Monday that its initial investigation into the drone strikes against two of the country's major oil production facilities revealed that Iranian weapons were used in the attack. The kingdom will now reportedly invite United Nations and other international "experts" to further investigate the situation.

Yemen's Iran-backed Houthi rebels initially claimed responsibility for the attacks, but the U.S. has accused Iran of orchestrating them. The U.S. and Saudi Arabia have alleged that Tehran supplies the Houthis with arms in Yemen's civil, however, so — even if the weapons are Iranian — it will likely remain unclear exactly what Iran's role was.

Trump, meanwhile, said there are "some very strong studies" being conducted on the attacks and that it looks like Iran is behind them. The president, when asked if the U.S. is ready for war, said the country is more prepared for a conflict than anyone in "any history."

He said the attack on Saudi Arabia could be "met with an attack many, many times larger" by the U.S. Tim O'Donnell

Shane Gillis won't be live from New York after all.

The comedian hired as a cast member for Saturday Night Live last week has just been fired following reports on his use of offensive racist and homophobic slurs, a spokesperson for the show announced.

"We were not aware of his prior remarks that have surfaced over the past few days," a spokesperson for SNL said, reports The New York Times' Dave Itzkoff. "The language he used is offensive, hurtful and unacceptable. We are sorry that we did not see these clips earlier, and that our vetting process was not up to our standard."

Gillis' SNL hiring was announced Thursday, but within hours, a clip from a September 2018 podcast in which he uses a racist slur against Asians spread on Twitter. Subsequent reports shed light on his use of other offensive language including homophobic slurs; in May 2019, he again used a racist slur against Democratic presidential candidate Andrew Yang.

In a statement last week, Gillis did not apologize for his remarks, although he said he would be "happy to apologize to anyone who's actually offended." On Monday, Gillis released another statement in which he brags that he's "a comedian who was funny enough to get SNL" and "that can't be taken away." After saying he respects SNL's decision, he makes light of the situation by writing he "was always a Mad TV guy anyway." Gillis again did not apologize. Brendan Morrow
