Robert MuellerLooks like we’ll be hearing from Robert Mueller after all. The former special counsel will testify publicly before the House Judiciary and Intelligence committees on July 17 about his almost two-year investigation into President Trump. Mueller agreed to testify after he was subpoenaed. This will be must-see TV and the most-anticipated congressional hearing in decades. Trump tweeted his response to the news: “Presidential Harassment!” The only other time we heard from Mueller was last month, when he explained that his investigation couldn’t clear the President of obstruction of justice and that Justice Department guidelines didn’t allow him to charge a sitting President. He also said if he testified, he wouldn’t go beyond what’s already in his report. Mueller’s testimony is probably the Dems’ best and last chance to politically weaponize the Russia scandal, CNN’s Stephen Collinson said.Nadler: Mueller won't let White House defy subpoenaNadler: Mueller won't let White House defy subpoenaNadler: Mueller won't let White House defy subpoenaJUST WATCHEDNadler: Mueller won’t let White House defy subpoenaReplayMore Videos …MUST WATCH

ImmigrationRead MoreThe humanitarian crisis on the US-Mexico border was brought into sharp, heartbreaking focus yesterday after this picture emerged. It’s a photo of a father and his young daughter who drowned over the weekend after they tried to cross the Rio Grande. They are facedown in the water on the banks of the Mexican side of the river, across from Brownsville, Texas. The little girl is tucked inside her father’s black shirt, with her small arm over his shoulder. The man’s widow said she watched helplessly as the pair drowned. The haunting image reminded many of the iconic photo of Aylan Kurdi, the 3-year-old Syrian boy whose body washed up in 2015 on a Turkish beach.Video captures drowned man and daughter near US borderVideo captures drowned man and daughter near US borderVideo captures drowned man and daughter near US borderJUST WATCHEDVideo captures drowned man and daughter near US borderReplayMore Videos …MUST WATCH

About 100 children were actually moved back to a facility in Clint, Texas, that was singled out for having major health and hygiene problems, including a reported lack of soap. Finally, the House passed a $4.5 billion border aid bill that contains provisions for the treatment of migrant children. The White House said it “strongly opposes” the bill and threatened to veto it.3. Campaign 2020Welcome to the Democratic debates pre-game show. Twenty Democrats will take to the stage in Miami tonight and tomorrow in the first official clash of the 2020 election cycle. The way the candidates have been sorted for this two-night event, Night One has the feel of an undercard, CNN’s Julian Zelizer says. The surging Elizabeth Warren will be center stage among a group of low-polling challengers. Night Two is more like a main event, with current front-runner Joe Biden facing off against high-polling competitors like Bernie Sanders, Pete Buttigieg and Kamala Harris. Here are answers to the top questions about every Democratic presidential candidate. Find out how the 2020 Dems are prepping for the first debate.

This eye-popping prediction comes from a new UN report, which says India will have more people than China by 2027. The two countries account for about 37% of the entire global population of 7.7 billion. By 2050, the world’s population will be 9.7 billion, the report predicts. A century earlier, that tally was 2.6 billion. More than half the predicted global population by 2050 will be clustered in just nine countries: the US, India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia and Egypt.China's senior citizens risk being left behind China's senior citizens risk being left behind China's senior citizens risk being left behind JUST WATCHEDChina’s senior citizens risk being left behind ReplayMore Videos …MUST WATCH

Zimbabwe has an estimated 84,000 elephants but can only afford to care for about 50,000, President Emmerson Mnangagwa said during a wildlife summit. Residents and farmers in rural communities also complain about elephants invading their lands and destroying crops. Angola might be a buyer, as that country looks to reintroduce elephant populations into wildlife areas where land mines have been removed. Zimbabwe also wants the global ban on the ivory trade lifted, so that it can sell its ivory and rhino horn stockpile. Selling the stockpile, which Mnangagwa says is worth $600 million, would help Zimbabwe fund conservation efforts.Saving elephants by crossing bordersSaving elephants by crossing bordersInside Africa Saving elephants by crossing borders B_00000000JUST WATCHEDSaving elephants by crossing bordersReplayMore Videos …MUST WATCH
