Shanmugam reacted to the attack by writing on his Facebook page that "Many, including many in the media, have condemned the thuggish actions of the protestors.... In Hong Kong, protestors took over the Legislative Council Building in 2019, vandalised it. They were lauded by some as freedom fighters, democracy heroes. Those lauding them include the very same media which now condemns the actions of the Washington protestors. What explains the different perspectives?" Attached to the post were screenshots of two different headlines in The Guardianone about the storming of Hong Kong's Legislative Council and the other about the storming of Capitol Hillhighlighting the apparent inconsistency.

We must not allow this." However, he also said there was a "certain fairness" to Trump's election fraud claims, while clarifying that it is "bad when they resort to storming and people die".
