The brother-in-law of a woman killed during the assault on the US Capitol by a mob seeking to overturn President Donald Trump's election loss said he blames Trump for the riot.
Rosanne Boyland, a 34-year-old resident of Georgia, was one of five people including a police officer who died in the rioting, according to police.
The cause of Boyland's death was not released but friend Justin Winchell told media she was trampled to death in a massive crowd surge when protesters clashed with police.
"I got my arm underneath her, that was pulling her out and then another guy fell on top of her and another guy was just walking (over her)," he said.
"I mean, there was people crushed."
Boyland's brother-in-law Justin Cave told Atlanta media his wife, Boyland's sister, had tried to persuade her not to attend the Trump rally in Washington.
Boyland was "passionate about her beliefs" and support of Trump and the family was grieving for others killed and injured in the rioting, he told a Fox television reporter.
"I've never tried to be a political person, but it's my own personal belief that the president's words incited a riot that killed four of his biggest fans last night and I believe that we should invoke the 25th Amendment (to remove Trump from office) at this time," Cave said.
A White House spokesman did not respond to a request for comment about Boyland's death.
Asked if Trump was to blame for his friend's death, Winchell said: "Does he have blood on his hands? No!"
Trump urged his supporters to come to Washington for the rally on Wednesday, the day the US House of Representatives and Senate were scheduled to certify his election loss to Joe Biden, then told them to walk to the Capitol "to fight".
Under the 25th Amendment, a president can be forcibly removed from power if the vice president and a majority of cabinet members agree that the president is unfit for office.
Democratic leaders in Congress have called for immediate impeachment proceedings if Vice President Mike Pence and Trump's Cabinet fail to seek to remove Trump from power.
Three other civilians were killed in the rioting on Wednesday.
Ashli Babbitt, a 35-year-old California native, was shot by a police officer in an incident that police are investigating.
Washington DC Police also said Kevin Greeson, 55, of Athens, Alabama, and Benjamin Phillips, 50, of Ringtown, Pennsylvania, died after experiencing medical emergencies.
A statement released by Greeson's family to local media said that the avid motorcycle rider had suffered a heart attack.
"Kevin was an advocate of President Trump and attended the event on January 6 to show his support," said the statement, quoted in The News Courier in Athens.
"He was excited to be there to experience this event,."
Phillips, a computer programmer, died of a stroke, the Philadelphia Inquirer reported.
Also killed was Capitol Police officer Brian Sicknick, 40, who suffered a stroke after injuries sustained "while physically engaging with protesters" the department said.
