Senate Minority Leader Chuck Schumer of N.Y., points to a reporter as he speaks to media after the Democratic policy luncheon on Capitol Hill, Wednesday, Oct. 10, 2018, in Washington. Senate Democrats briefly turned the chamber's subject to health care Wednesday, just four days after lawmakers' nasty war over confirming Supreme Court Justice Brett Kavanaugh. And while Democrats lost the vote, they hope they've gained a message that will bolster their chances of winning Senate control in next month's elections. (AP Photo/Alex Brandon)

FILE - In this Oct. 11, 2017 file photo, a Pacific Gas & Electric crew works at restoring power following a wildfire along the Old Redwood Highway in Santa Rosa, Calif. California Gov. Jerry Brown signed a measure Friday, Sept. 21, 2018, allowing utilities to bill their customers to pay for future legal settlements stemming from devastating 2017 wildfires, even if the blazes are blamed on the company's mismanagement. The bill is aimed at preventing bankruptcy for Pacific Gas & Electric Co. The nation's largest utility by revenue faces billions of dollars in liability if investigators determine its equipment caused the Tubbs Fire that destroyed thousands of homes and killed 22 people in Santa Rosa last year.

FILE - In this Sept. 5, 2018, photo, Sen. Jon Kyl, R-Ariz., waits to be sworn-in by Vice President Mike Pence during his ceremonial swearing-in at the Old Senate Chamber on Capitol Hill, in Washington. After years of trying to demolish former President Barack Obama’s prized health care law, GOP leaders still lack the votes to succeed. Kyl says he’d vote to repeal the “Obamacare” health care law. That’s one additional Republican ready to obliterate the statute because his predecessor, the late Sen. John McCain, helped derail the party’s drive with his fabled thumbs-down vote last year. It could well be too little, too late. (AP Photo/Cliff Owen)
