President Trump's approval rating in his second term has reached a record low. According to a Times Sienna poll released this morning, just 37% of voters approve of how Trump is handling his job as president. That's less than at any point since he took office last year. Trump's approval rating has dropped four points since January alone, and a majority of voters seem deeply skeptical of how he's handling some of the country's most pressing issues. For example, 64% of voters disapprove of how he's handled the economy and 65% say they disapprove of how he's handled the war in Iran. Still, Republicans broadly approve of Trump's job performance and how he's handled the war. And this weekend, there was more evidence that the president has continued to keep a tight grasp on his party. In Louisiana on Saturday, Republican Senator Bill Cassidy, who's clashed with the president, lost his primary election after being beaten by a Trumpbacked candidate. Cassidy was one of a small handful of Republicans who voted to convict Trump in his impeachment trial after January 6th.

First, a new analysis estimates that President Trump's mass deportation campaign has separated more than 100,000 children from their parents. A vast majority of those kids are US citizens. The report from the Brookings Institution suggests that federal statistics about family separations have been an undercount. In a statement, the Department of Homeland Security said that when parents of US-born children are detained, they're given a choice. leave the country with their kids or place them with someone living in the US legally. And the Times has learned that for the past four months, the US has been quietly negotiating over the future of Greenland. "We need Greenland for national security. And if you take a look at Greenland, you look up and down the coast, you have Russian and Chinese ships all over the place." President Trump has repeatedly said he wants to seize the island, which is partly controlled by Denmark. Among other things, the US has been trying to extend a long-standing military arrangement to allow US troops to stay in Greenland indefinitely. And the Trump administration wants effective veto power over any major investment deals there to potentially box out countries like Russia and China.

The World Health Organization has declared that a new outbreak of the Ebola virus is a global health emergency. As of yesterday, there have been reports of more than 300 suspected cases in the Democratic Republic of Congo, including nearly 90 deaths. And the WHO has warned the scale of the outbreak could be far larger than has been detected. The rare type of the virus that's taken hold now has no targeted vaccine or treatment. It has a mortality rate of 25 to 50%. Matthew Biggs says that the part of Congo where cases have been spreading has been in political turmoil. A few years ago, the country's president launched a widespread crackdown in the region, declaring a state of siege, effectively martial law. Trust in the authorities is a critical factor in containing the spread. But the other thing is obviously in a state of siege, health care services and health care facilities are not as strong as they need to be. Matt says there's another factor that could potentially complicate the response: The Trump administration's push to slash foreign aid. USAID was a key player in containing previous Ebola outbreaks, but the White House shuttered the department last year.

In Colombia, a new tourism industry has been sparked by apps for bird watchers. It's known as aven tourism. In recent years, more and more people have been learning about Colombia's remarkable biodiversity as the apps Merlin and eBird have brought birding to the masses. For example, Merlin, which lets you identify birds using a photo or recording of their song, has been downloaded by nearly 40 million people. On eBird, the map of Colombia is bright red, showing that close to 2,000 bird species have been recorded there. To keep up with a new wave of app toading aven tourists, some Colombians are now turning to the birding business. Some local bird enthusiasts say they hope that will help preserve the country's environment by creating an incentive to protect habitats. One woman told the Times that she and her husband spent years using chainsaws to cut down their trees to make charcoal, but now she says she stopped to try and keep the birds and the tourists around.
