LifeWay Christian Resources announced Wednesday it will close all 170 of its retail stores this year and focus on digital sales. In January, the publishing arm of the Southern Baptist Convention said it would reduce its brick-and-mortar locations due to declining customer traffic and sales. “While we had hoped to keep some stores open, current market projections show this is no longer a viable option,” acting President and CEO Brad Waggoner said in a statement.

After pushback from local politicians, Amazon said it will no longer build a headquarters in New York City. The Seattle-based online retailer spent a year conducting a highly publicized search in which cities tried to woo the company with promises of favorable tax policies.

Amazon CEO Jeff Bezos in a blog post Thursday claimed to be the target of extortion and blackmail by the publisher of the National Enquirer. Bezos, 55, said the tabloid threatened to publish explicit personal photos of him unless he stopped investigating how the Enquirer obtained texts between him and his mistress. The National Enquirer on Jan. 9 published a story about Bezos and his affair with former TV anchor Lauren Sanchez, who is married. That same day, Bezos announced on Twitter that he and his wife of 25 years, MacKenzie Bezos, were planning to divorce.

Hiring has accelerated since last summer despite December job growth coming in below predictions.

The Pacific Gas and Electric Company said Monday it will file for bankruptcy in the face of massive potential liabilities for deadly California wildfires in recent years.
