Sen. Ted Cruz (R-Texas) and his challenger, Rep. Beto O'Rourke (D-Texas), wrangled at a contentious debate in Dallas Friday night. And the fatal shooting of Botham Jean — the black man killed in his apartment by a white Dallas police officer who says she mistook it for her own home — was a key issue of division between the candidates.

The evening of the debate, Cruz's Twitter account shared a video of O'Rourke speaking to wild cheers in a majority-black church. The clip shows an impassioned O'Rourke arguing Jean's case has yet to see justice. "How can we continue to lose the lives of unarmed black men in the United States of America at the hands of white police officers?" he asks.

The tweet's caption suggests the Cruz campaign sees this plea for better police accountability and a transparent public investigation into Jean's killing as self-evidently damning.

At the debate itself, Cruz argued his opponent consistently "sides against the police," claiming O'Rourke has "described law enforcement as modern day Jim Crow." O'Rourke's actual comment, made Wednesday, referenced the book The New Jim Crow to note black Americans are subject to demonstrable discrimination in the U.S. justice system.

"With the tragic shooting death of Botham Jean, you have another unarmed black man killed in this country by law enforcement," O'Rourke said at the debate. "Now, no member of law enforcement wants that; no member of this community wants that; but we've got to do something better than what we've been doing so far."

Latest polls show Cruz and O'Rourke are in a dead heat. Watch their full debate below; the discussion of policing begins around the seven-minute mark and continues through minute 16 with a discussion of NFL players' pre-game protests of police brutality. Bonnie Kristian

Federal Emergency Management Agency (FEMA) Administrator Brock Long will not be fired for his inappropriate use of cars owned by the government, Homeland Security Secretary Kirstjen Nielsen said Friday.

Long used federal vehicles and personnel for his weekend commutes from Washington, D.C., to North Carolina. He had a driver take him home, and reportedly brought aides with him, housing them in hotels using taxpayer money. He was investigated by the Department of Homeland Security's inspector general.

Nielsen said Long, who will repay the government an undisclosed amount, was acting in line with a longstanding but unofficial FEMA practice intended to keep the administrator accessible in case of crisis. That practice has now been discontinued.

"We had a productive conversation where we discussed my expectations regarding the agency's use of government vehicles going forward," Nielsen's statement said. "The administrator acknowledged that mistakes were made, and he took personal responsibility." Bonnie Kristian

China on Friday canceled scheduled trade negotiations with the United States, citing the Trump administration's tariff escalations. President Trump announced a new round of tariffs on $200 billion of Chinese imports Monday and is expected to target another $257 billion in products this coming week.

"Nothing the U.S. has done has given any impression of sincerity and goodwill," said Chinese Foreign Ministry representative Geng Shuang. "We hope that the U.S. side will take measures to correct its mistakes."

China also slammed new U.S. sanctions punishing Beijing for purchasing weapons from Russia. "The U.S. approach is a blatant violation of the basic norms of international relations, a full manifestation of hegemony, and a serious breach of the relations between the two countries and their two militaries," said a Chinese Defense Ministry statement promising "consequences."

President Trump seemed to respond Friday night at a rally in Missouri to the day's report that Deputy Attorney General Rod Rosenstein considered invoking the 25th Amendment to remove him from the Oval Office.

"Just look at what is now being exposed in our Department of Justice and the FBI. Look at what's going on," Trump said, never mentioning Rosenstein by name. "And I want to tell you, we have great people in the Department of Justice. We have great people. These are people, I really believe, you take a poll, I gotta be at 95 percent. But you got some real bad ones. You've seen what's happened at the FBI. They're all gone. They're all gone. They're all gone. But there's a lingering stench, and we're going to get rid of that too."

Trump also again weighed in on the sexual assault allegation against his Supreme Court nominee. Brett Kavanaugh is a "fantastic man" who was "born for the U.S. Supreme Court," the president said, promising his audience the confirmation would go through. "We have to fight for him, not worry about the other side," Trump said. "And by the way, women are for that more than anybody would understand."

A Wall Street Journal/NBC News poll published Thursday found a plurality of Americans now oppose Kavanaugh's nomination, and his rising unpopularity is significantly due to shifting attitudes among women since the allegation came to light. Bonnie Kristian

At least 24 people were killed and more than 50 injured Saturday when gunmen opened fire on a military parade in the Iranian city of Ahvaz, state media reported. Civilians, including children and members of the press, were reportedly among the dead.

"Terrorists began shooting from a long distance while inside the park, at the armed forces as well as civilians watching the parade," said Brig. Gen. Abolfazl Shekarch. Three of the attackers were killed and one was arrested, and the attack was claimed by the Patriotic Arab Democratic Movement, a separatist organization.

Officials said the shooters were disguised as military members and accused Saudi Arabia of connection to the attack. "Terrorists recruited, trained, armed & paid by a foreign regime have attacked Ahvaz. Children and journos among casualties," tweeted Iranian Foreign Minister Mohammad Javad Zarif. "Iran holds regional terror sponsors and their US masters accountable for such attacks." Saudi Arabia has not responded to the allegation. Bonnie Kristian

Senate Judiciary Committee chair Chuck Grassley (R-Iowa) granted an extension late Friday for Christine Ford to decide whether to testify about her sexual assault allegation against Supreme Court Nominee Brett Kavanaugh. Grassley announced his choice with a series of tweets, sometimes addressing Ford or Kavanaugh directly:

The previous deadline, already an extension, was Friday at 10 p.m. Eastern. Ford's attorney asked for an additional day, labeling this a "modest request" to correct the Judiciary Committee's "cavalier treatment of a sexual assault survivor who has been doing her best to cooperate" with the Senate.
