Former President Donald Trump Friday filed a federal lawsuit challenging a subpoena from the House committee investigating the Capitol attack on Jan. 6, 2021, according to media reports, officially sparking a legal battle with the panel that has accused him of being a central figure in the riot. The requests included records of phone calls, texts or Signal messaging app communications placed or received by Trump between the 2020 election and the riot. Among those targeted in the communications are members of Congress and advisers, including political operative Roger Stone and personal lawyer Rudy Giuliani. The committee conducted more than 1,000 interviews and depositions, and collected hundreds of thousands of pages of documents, to chronicle what led to the Jan. 6, 2021, attack and what happened that day.
