Trump's 'Big Lie' election fraud claims will be the focus of Monday's Jan. 6 hearing

The second hearing of the congressional committee investigating the Jan. 6, 2021, attack on the U.S. Capitol on Monday will focus on former President Donald Trump's insistence that his 2020 election defeat was the result of widespread fraud, an unfounded allegation known as the "Big Lie."

Avenatti, 51, already faces five years in prison after being convicted in February of fraud and identity theft for diverting nearly $300,000 in book proceeds meant for Daniels, and convicted in February 2020 of trying to extort up to $25 million from Nike Inc.

Exclusive-New York City to auction sanctioned Venezuelan mogul's apartment

Gun reform deal forged by U.S. senators, with key Republican backing

In a potential breakthrough toward the first significant new U.S. gun law in decades, a bipartisan group of senators on Sunday announced an agreement on a framework for a firearms safety bill with enough Republican support to advance in the narrowly divided Senate.
