Embattled Virginia Lt. Gov. Justin Fairfax compared himself to Jim Crow-era lynching victims in a surprise speech Sunday, as he resists widespread calls to resign prompted by allegations of sexual assault. "I've heard much about anti-lynching on the floor of this very Senate, where people were not given any due process whatsoever, and we rue that," Fairfax said, referencing legislation the General Assembly passed expressing "profound regret" for lynchings in Virginia between 1877 and 1950. "And we talk about hundreds, at least 100 terror lynchings that have happened in the Commonwealth of Virginia under those very same auspices. And yet we stand here in a rush to judgment with nothing but accusations and no facts and we decide that we are willing to do the same thing," Fairfax said.

The attorneys general of the District of Columbia and Maryland plan to file subpoenas Tuesday seeking records from the Trump Organization, the Treasury Department and dozens of other entities as part of a lawsuit accusing Donald Trump of profiting off the presidency.

A report compiled by private researchers and released by the Senate intelligence committee Monday says that "active and ongoing" Russian interference operations still exist on social media platforms, and that the Russian operation discovered after the 2016 presidential election was much broader than once thought.

To Democratic supporters, the Green New Deal is a touchstone, a call to arms to combat climate change. To Republican opponents, it’s zealous environmentalism, a roadmap to national bankruptcy.

A visit from friend and fellow former president, Bill Clinton, inspired him to wear a pair emblazoned with Clinton's face. He wore Houston Texans' socks when meeting with the head coach. At the funeral for his wife, Barbara Bush, former President George H.W. Bush wore socks featuring books as a tribute to her work promoting literacy. Bush, who was a naval aviator in World War II, will be buried this week wearing socks featuring jets flying in formation — a tribute, his spokesman says, to the former president's lifetime of service.

The mother of a 9-year-old Illinois boy who is charged with murder in connection with a mobile home fire that killed five people says the child is "not a monster." During interviews Thursday with local and national media organizations, the woman said her son "made a terrible mistake," adding that "he's a child."

The Federal Reserve has cut its benchmark interest rate again, big news for the U.S. economy but something that will likely have a muted impact on Americans' personal finances, experts say. That's because the reduction doesn't offset the increases of recent years. And as the key rate creeps closer to zero, financial institutions are less eager to pass borrowing benefits along. Lower rates could also further dampen the perks of savings.

President Donald Trump has picked budget director Mick Mulvaney to be his acting chief of staff, ending a chaotic search in which several top contenders took themselves out of the running for the job. It was not immediately clear why the president decided to make Mulvaney's appointment temporary. One senior White House official said there was no time limit on the appointment and Mulvaney would fill the role of chief of staff indefinitely, regardless of the "acting" title.
