Oath Keepers 'could not accept Biden win'

A prosecutor has urged a jury to convict four members of the far-right Oath Keepers of seditious conspiracy, saying they plotted to stop the United States Congress from certifying the 2020 election because they could not accept President Joe Biden's victory.

"The defendants could not let the election stand. They could not let Biden come to power," federal prosecutor Louis Manzo told the jury on Wednesday.

Thousands of supporters of Republican then-president Donald Trump stormed the Capitol on January 6, 2021, in an attempt to overturn Democrat Biden's victory.

In closing arguments, Manzo pointed across the room to defendants Roberto Minuta, Joseph Hackett, David Moerschel and Edward Vallejo and accused the men of up-ending America's two-century record of "the routine peaceful transfer of power".

"Our democracy was under attack, but for these defendants, it was everything they trained for," he said.

Defence lawyers for the four deny their clients hatched a plot to block the certification of the 2020 election and have accused prosecutors of cherry-picking evidence to present what they called a misleading narrative.

The closing arguments marked the end of the second major seditious conspiracy trial stemming from the attack.

Four people died during the chaos and five police officers died afterward, while about 140 officers were injured and the Capitol sustained millions of dollars in damage.

The Oath Keeper members are accused of conspiring to block Congress from certifying Biden's election victory.

Seditious conspiracy is a rarely prosecuted Civil War-era statute that carries up to 20 years in prison if convicted.

In November, a jury convicted Oath Keepers founder Stewart Rhodes and a Florida chapter leader of seditious conspiracy but acquitted three other Oath Keeper defendants of the charge.

All five Oath Keepers in that case, however, were convicted of obstructing Congress from certifying the electoral votes - a charge that can also carry up to 20 years.

A third seditious conspiracy trial against five members of the far-right Proud Boys group, including its former chairman Henry "Enrique" Tarrio - is under way in the same courthouse.
