Two US Army National Guard members have been removed from duty during Joe Biden's presidential inauguration because of ties to far-right militias, according to Associated Press.
A US Army official and a senior US intelligence official confirmed the decision to AP on the condition of anonymity due to Defense Department media regulations.
They did not say what fringe group the Guard members belonged to or what unit they served in.
A spokesman for the National Guard Bureau told AP: "Due to operational security, we do not discuss the process nor the outcome of the vetting process for military members supporting the inauguration."
The heightened security comes after the riots on 6 January when Donald Trump supporters stormed the Capitol Building.
