A columnist who has worked at The Washington Post for four decades resigned on Monday after the newspaper’s management decided not to run her commentary critical of owner Jeff Bezos’ new editorial policy.

Ruth Marcus, who has worked at the newspaper since 1984, wrote that “it breaks my heart to conclude that I must leave.” Her resignation letter was first reported by The New York Times.

Her exit is fallout from the billionaire owner’s directive that the Post narrow the topics covered by its opinion section to personal liberties and the free market.

A Post spokeperson said Monday that “we’re grateful for Ruth’s significant contributions to The Washington Post over the past 40 years. We respect her decision to leave and wish her the best.”

Mortgage lender Rocket Cos. has agreed to acquire online real estate brokerage Redfin in an all-stock deal valued at $1.75 billion.

The transaction, announced Monday, gives one of the nation’s largest mortgage lenders an in-house network of more than 2,000 real estate agents across 42 states and Redfin’s popular home and rental housing listings platform, which draws nearly 50 million monthly visitors.

The deal values Redfin at $12.50 per share. Shares in Seattle-based Redfin soared 68.5% in morning trading to $9.81 per share, while shares in Detroit-based Rocket Cos. slumped 15%.

Detroit-based Rocket expects the acquisition will save the company $140 million in costs by eliminating duplicative operations and other expenses
