PROBLEM: Hamilton Police Sgt.  Michael Virga  was on patrol around 3 a.m. when  he  saw  it . " It  was a pinpoint in the sky  then a bright lime green streak and then  it  disintegrated "  he  tells NPR.
 He  thought at first maybe  it  was a firework but was jolted enough to pull over and roll back the video. And sure enough  it  had recorded a clear view of the display. Virga said a later look at the website of the American Meteor Society  which tracks such sightings  confirmed that many others also saw the meteor.
Of his own experience   Virga  said it was a matter of simply "being in the right place at the right time." After the department posted the video to Facebook  he says  social media have been lighting up about it too.
"It's something different "  Virga  says.

PROBLEM: 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.
This undated photo provided by St. Charles County Department of Corrections via KMOV shows the Sayfullo Saipov.

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.

Republican leaders expect to hold a vote early next week on the sweeping tax-cut plan that is currently in a House-Senate negotiation. The Senate version initially passed with 51 votes. If  McCain  missed the vote on final passage  Republicans would not be able to afford a single additional defection or absence to pass the legislation.
â Senator McCain  is currently receiving treatment at Walter Reed Medical Center for normal side effects of  his  ongoing cancer therapy â  his  office said in a statement. âAs ever   he  remains grateful to  his  physicians for their excellent care  and  his  friends and supporters for their encouragement and good wishes.â
