Harris puts Biden's race record on trial in Round 2 of Dem primary debate

Democratic presidential primary front-runner Joe Biden ran into a formidable challenge at Thursday night’s debate from U.S. Sen. Kamala Harris, who tapped into her prosecutor toolbox to put his race record on trial following the controversy over his comments on segregationist senators. In perhaps the most heated moment of the night, Harris told Biden she doesn’t believe he is a “racist” but considers his recent comments about being able to work with segregationist senators early in his career “hurtful.”

Biden has said he disagreed with the senators on segregation, but was still able to work with them in the Senate. But that explanation did not deter Harris during Thursday's debate. “You worked with them to oppose busing,” Harris said, referring to efforts to limit orders for school desegregation by busing. In an emotional moment, she told her own story of being bussed as a little girl in California. Biden fired back that Harris’ comments were a “mischaracterization of my position across the board.”

Biden, though, mostly kept his focus on the candidate he really wants to face -- President Trump. He repeatedly invoked the name and record of his popular running-mate Barack Obama and brushed back swipes at his age from long-shot candidate Rep. Eric Swalwell, who repeatedly called on him to "pass the torch." It's unclear whether the clash with Harris might damage Biden -- considering most prior controversies have not dinged his poll numbers -- or simply give Harris some needed momentum.

Meanwhile, Sen. Bernie Sanders avoided any direct clash with Biden. He spent much of the night defending his big-government agenda against questions from moderators and criticism from more centrist leaning – and lower-polling – candidates. Several rivals took issue with some of Sanders’ socialistic policies, like "Medicare-for-all" and free college tuition. South Bend, Ind., Mayor Pete Buttigieg broke with Sanders in saying while he supports free college for children of low and middle income, “I just don’t believe it makes sense to ask working-class families to subsidize even the children of billionaires.”

Still, the debate also made clear how Democrats have moved to the left on issues relating to immigration. All 10 Democrats raised their hands when asked if their government health care plan would cover illegal immigrants. Pollster Frank Luntz summed it up this way on "The Ingraham Angle" on Thursday: "This is not your parents' Democratic Party."

Trump likes what he saw in the Democratic debate from afar

At one time, some pundits were predicting that Democrats could defeat President Trump and the Republican Party on health care. However, thanks to the Democratic Party's stance on health care for illegal immigrants, Trump and Republicans are feeling very confident. While attending the G-20 Summit in Osaka, Japan, the president said Democratic White House contenders’ willingness to extend government health care to illegal immigrants in America will get him reelected. Trump tweeted: “All Democrats just raised their hands for giving millions of illegal aliens unlimited healthcare. How about taking care of American Citizens first!?” He then added: “That’s the end of that race!”

Friends of missing Utah student spot activity on Instagram account

The search for missing Utah student Mackenzie Lueck has taken a peculiar twist. Friends of Lueck told Fox News that they noticed activity on her Instagram account on Wednesday and turned the information over to authorities. Lueck’s personal Instagram account liked a page called “fatherless,” around noon, and her friends quickly took screengrabs to document the activity and turn over to police. The @fatherless handle had more than 47,000 followers as of early Friday but was following only 15 accounts — not including that of Lueck.

The 23-year-old woman was last seen meeting an unknown individual around 3 a.m. June 17 at a park in Salt Lake City after being dropped off by a Lyft driver. She hailed the ride after flying in from Los Angeles – where she had attended her grandmother’s funeral. While the Lyft driver has been cleared, police searched the Salt Lake City home of the man they said is a "person of interest" for about 19 hours the past two days. Police said they are also looking for a mattress and box spring removed from the home last week.

Iraqi general: Accused Navy SEAL did not stab ISIS prisoner

The Iraqi general at the scene of an alleged murder of an Islamic State prisoner in Iraq in 2017 testified in a deposition video played in court Thursday that Navy SEAL Eddie Gallagher never stabbed the teenage detainee. In a recording made earlier this month, Maj. Gen. Abbas al-Jubouri testified he never saw Gallagher stab the detainee in the neck. Gallagher served alongside Abbas’ unit in an advise-and-assist capacity in Mosul. Abbas told the defense lawyer if had he witnessed improper conduct from SEALs, he would have taken action. Last week, a Navy SEAL, Special Operator 1st Class Corey Scott, testified that Abbas’ unit tortured, raped and murdered prisoners. Scott said he killed the ISIS prisoner by putting his thumb over the detainee’s breathing tube in order to save him from falling into the hands of Abbas’ unit.

France highly motivated in Women's World Cup showdown with Team USA

The United States has its ranking and its trophies, and that's all the motivation France needs. The Americans face the French on Friday night at the Women's World Cup, a match that's been described as a final in the quarterfinals. It really has it all: The defending champions against the upstart hosts. The City of Lights. A sellout crowd. "They've got a great trophy cabinet and we still have everything to prove," French captain Amandine Henry said. The only downside? The country is in the midst of a heat wave and temperatures are expected to soar into the 90s, although a 9 p.m. local time start should bring some cooling. France is seeking to become the first nation to simultaneously hold the men's and women's World Cup trophies. (The men won last year in Russia.) The United States already has three FIFA Women's World Cup trophies, most of any nation.
