GeoEcon 101: In the midst of an economic slowdown and a stock market slump, China devalued its currency for the second day in a row. The Central Bank dropped the value of the yuan, by 1.6 percent against the US dollar. They lowered the value by 1.9 percent yesterday.

A less valuable yuan makes Chinese goods cheaper to buy in America, threatening American jobs and possibly slowing the economy. The Dow Jones dropped more than 200 points on the news yesterday and world markets fell again today.

China is swimming against the tide to hit its targeted 7 percent growth this year, and the currency devaluation is like a steroid injection.

Police Beat: The rookie Arlington, Texas police officer who shot and killed an unarmed college football player inside a car dealership has been fired for “inappropriate judgment.” Officer Brad Miller, 49, was still in training when he killed 19-year-old Christian Taylor last Friday.

World: Fragments of a Russian-made anti-aircraft missile were found among the wreckage of the Malaysian airliner that went down in Ukraine just over a year ago, according to investigators in the Netherlands.

Both Russia and the rebels deny it.

Politics: With the Trumpstorm having blown over for at least a day, presidential candidates from both parties tried to steer back to some substantive issues.

Florida’s Jeb Bush came out swinging at the Ronald Reagan Library in California last night, saying former Secy. of State Hillary Clinton allowed the withdrawal of American troops, letting Iraq fall apart while ISIS rose to power. Bush said Clinton “stood by as that hard-won victory by American and allied forces was thrown away.” He takes a risk opening debate about the controversial war spurred by his brother George.

Meanwhile Clinton can’t seem to shake off questions about her use of a private email server while she was secretary of state. She announced she’s handing over to the Justice department her whole server and a thumb drive containing the emails.

Donald Trump called for a simplified tax code and possibly even a flat tax on income. “Put H&R Block out of business,” he said.

OK, Trump didn’t completely take the day off from name-calling. He said Democrat Bernie Sanders was “weak” for letting protesters take over his microphone at a rally. And he took credit for attracting 24 million viewers to last week’s debate. “Who do you think they were watching? Jeb Bush?”

And finally, losing in the money-raising polls, Rick Perry has stopped paying his campaign staff. He’s only raised about $1 million but a spokeswoman swears he’s in it for the longer haul.

Deadliest: Tony Lara, the fishing captain who stepped in for the late Captain Phil Harris on the Cornelia Marie in the Discovery series “Deadliest Catch,” died in a private home while attending the 75^th annual Sturgis motorcycle rally in South Dakota. He was 50.

As of 6 am Saturday, the rally had the 12 fatal crashes, 140 injury crashes and 74 non-injury accidents.
