After losing the Democratic primary in New York's 14th congressional district Tuesday night, Rep. Joe Crowley picked up his guitar and dedicated a song to the victor.

"This is for Alexandria Ocasio-Cortez," Crowley said, before launching into "Born to Run." Ocasio-Cortez, 28, defeated Crowley, a 10-term congressman, in her first ever political race. Crowley also tweeted his congratulations to Ocasio-Cortez, and said he looks "forward to supporting her and all Democrats this November. The Trump administration is a threat to everything we stand for here in Queens and the Bronx, and if we don't win back the House this November, we will lose the nation we love."

Crowley's loss came as a surprise to many, as he was one of the top Democratic lawmakers in the House of Representatives. "It has been the honor of a lifetime to represent Queens and the Bronx," he said. "I am proud of the race we ran and, more importantly, proud of all the work we've done to advance this community."

A poster linking Rep. Ilhan Omar (D-Minn.) to the Sept. 11 terrorist attacks spotted in the West Virginia statehouse sparked outrage on Friday.

The poster showed a photograph of Omar beneath an image of the attacks, arguing that the newly elected congresswoman, a Muslim and a refugee from Somalia, was "proof" that Americans have forgotten Sept. 11.

The image was first spread by Mike Pushkin, a Democratic member of the West Virginia House of Delegates, who said someone saw the poster and sent him a picture of it. "I thought it was racist and it was wrong," Pushkin said. The poster eventually led to an altercation between some Democratic lawmakers and the House's sergeant-at-arms, who was accused of making an "anti-Muslim" remark and subsequently resigned.

Pushkin said no Republican lawmakers condemned the paper, The Washington Post reported. But several responded to the incident by arguing that it was a matter of free speech. Tim O'Donnell

It was a rough week for President Trump — he failed to secure a deal with North Korean leader Kim Jong Un in Vietnam and his former personal lawyer testified against him before Congress. But he was back in his element at the Conservative Political Action Conference (CPAC) in National Harbor, Maryland, on Saturday, speaking before a raucous crowd.

The president acknowledged early in his remarks that he was going off script because "this is how I got elected," and, "if we don't go off script, our country is in big trouble."

Go off script he did. When Trump first appeared, he gave the American flag standing on stage a hug. Topics meandered throughout — from trade with China and the Green New Deal to Hillary Clinton and William McKinley. He even lamented how he has to convince his childhood friends to call him "Donny", instead of "Mr. President."

Trump also used his time on stage to criticize the media and Special Counsel Robert Mueller's Russian election meddling investigation, as well as to praise political allies like Rep. Jim Jordan (R-Ohio) and Rep. Mark Meadows (R-N.C.).

Sen. Bernie Sanders (I-Vt.) officially launched his presidential campaign in his hometown of Brooklyn on Saturday.

"Thank you all for being part of a political revolution which is going to transform America," he told a crowd of supporters. "No, no, no, it is not Bernie, it is you. It is us together," Sanders continued as the crowd began chanting his name.

"And I want to thank you for being part of a campaign which is not only going to win the Democratic nomination, which is not only going to defeat Donald Trump — who is the most dangerous president in modern American history — but with your help we are going to transform this country and finally create an economy and a government which works for all of us, not just the 1 percent."

Sanders announced his candidacy for the 2020 Democratic primary in February and is scheduled to make his next campaign stop in Chicago on Sunday, where he is expected to discuss how his upbringing and education shaped his political views. Other major Democratic candidates include Rep. Tulsi Gabbard (Hawaii) and Sens. Elizabeth Warren (Mass.), Kamala Harris (Calif.), Cory Booker (N.J.), Amy Klobuchar (Minn.), and Kirsten Gillibrand (N.Y.).

Canada is stuck in the middle of an argument between the United States and China and, for now, Prime Minister Justin Trudeau's government is sticking with its neighbors to the south.

The Canadian government approved a U.S. extradition request for Meng Wanzhou, the chief financial officer of Chinese tech giant Huawei, on Friday. The decision drew ire from Beijing — the Chinese embassy in Ottawa relayed that the government is "utterly dissatisfied" and "firmly opposes" the decision.

Meng, who was detained in December in Vancouver, is accused of lying to banks about Huawei's dealings with Iran in violation of U.S. sanctions placed upon the country. China believes the accusations are part of a U.S. political stunt to hurt a potential competitor to U.S. tech companies.

Although the Canadian government approved the request, it could be years before Meng is sent to the U.S. since Canada's justice department allows many decisions to be appealed.

Meng is due in a Vancouver court on March, when a date will be set for her extradition hearing. Tim O'Donnell

The U.S.-backed Syrian Democratic Forces (SDF) said on Saturday they are close to expelling the Islamic State from its last bastion of territory in Baghouz, Syria.

The battle is expected to be over "soon," said Mustafa Bali, the head of the Kurdish-led SDF's media office. This round of fighting began on Friday after the last remaining civilians evacuated Baghouz, leaving only ISIS fighters in the territory. Most of the evacuees were women and children — they were separated from the men, who were taken in for interrogation. An estimated 10,000 civilians have evacuated the territory since Feb. 20, many of them hailing from other countries, Al Jazeera reports.

An SDF victory would be significant, per Reuters, as ISIS once held a large swath of territory in the region. But the insurgents are expected to remain a guerrilla threat despite losing their last stronghold. Tim O'Donnell

The U.S. military will no longer conduct large-scale drills with South Korea, NBC News and The Wall Street Journal reported Friday, each citing two unnamed defense officials.

Instead of major annual exercises, the officials said, U.S. and South Korean forces will cooperate on smaller, less costly training projects. "The U.S. has identified ways to mitigate potential readiness concerns by looking at required mission tasks versus having to conduct large-scale exercises," one official told NBC.

The large-scale exercises were suspended last year after President Trump promised to stop the "provocative" war games during his first summit with North Korean leader Kim Jong Un in Singapore. Another set of drills was canceled in October to further diplomatic progress with Pyongyang. Bonnie Kristian
