SAN FRANCISCO â Sayfullo Saipov  the 29-year-old suspect in Tuesday's deadly New York truck attack  earned money the way many gig economy works do. He drove for Uber.
But the fact that  Saipov  raised no flags for the ride-hailing company when it conducted its standard background check shows just how difficult it is to screen for potentially criminal behavior if there is no track record.
 Saipov  drove more than 1 400 trips for Uber in the past six months. Authorities continue to investigate the suspect  who came from Uzbekistan in 2010 and settled in Paterson  N.J. To date  his biggest offense seems to be from 2015  when he was cited by police for towing a trailer that was too long.

The company's response to that incident was the same as its statement after  Saipov  rammed  his  rented truck into bicyclists  killing 8. An Uber representative said the company was "horrified" at the senseless act of violence as was cooperating with federal officials.
Uber said  Saipov  had been banned from the Uber app.

LONDON â  The Rev. Billy Graham  who died Wednesday at age 99   was friend to a number of world leaders â and counted Britainâs Queen Elizabeth II among them.
âNo one in Britain has been more cordial toward us than  Her Majesty Queen Elizabeth II â Graham  the world's best-known evangelist   wrote in Just As I Am   his  1997 autobiography.

The Grahams visited Britainâs royal family at locations including two of the queenâs homes â Windsor Castle  near London  and the Sandringham estate  in eastern England  the Billy Graham Evangelistic Association said in an article to mark the monarchâs 90th birthday in 2016.
âHer official position has prevented her from openly endorsing our crusade meetings. But by welcoming us and having me preach on several occasions to the royal family at Windsor and Sandringham  she has gone out of her way to be quietly supportive of our mission â  Graham  wrote in  his  autobiography.

The relationship between  Graham  and the British monarch was depicted in the Netflix series The Crown â although some historians say a few creative liberties were taken.
âI think heâs rather handsome â Claire Foy  who plays the queen on the show  tells her husband  Prince Philip  after seeing  Graham  preach.
âYou do speak with such wonderful clarity and certainty â she later tells  Graham   played by Paul Sparks.
 Graham   who suffered from ailments including cancer and pneumonia  died Wednesday at his home in North Carolina  where he retired in 2005.
Justin Welby  the leader of the Church of England and head of the worldwide Anglican Church  said in a statement that  Graham  has "few equals."

"It doesn't matter what the causes are " said  Art Hogan   managing director and chief market strategist at B. Riley Financial  a financial service company. "You've got some great buying opportunities " he told CNBC.
"We're selling everything because we're so concentrated in our ownership of stocks and ETFs that we're creating dislocations that are going to be massive opportunity for active managers and stock pickers "  Hogan  said.
Increased volatility  or uncertainty in the size and direction of market changes  is good for banks   Hogan  said Thursday during "Power Lunch." Add that to rising interest rates and net interest margins and what  Hogan  called a "lighter regulatory touch" and financials are a bargain.
"They're being sold like there is no economy or no economic growth going on "  Hogan  said. "They're being thrown out with the bath water."
