Andy Aplikowski, who was until recently the political director of the Minnesota Republican Party, has called on President Trump to resign.
Extremists supporting the president have breached the U.S. Capitol in an apparent bid to prevent Congress from certifying the presidential election result in favor of Joe Biden.
Earlier on Wednesday, Trump appeared at a rally outside the White House in which he encouraged the crowd to walk to the Capitol and "demand" Congress "confront this egregious assault on our democracy," saying they need to "show strength" and "fight much harder."
Protesters were involved in violent clashes with police prior to breaching the Capitol, prompting some Capitol police to pull guns inside the chambers.
As the ugly scenes were shared around the world, the former political director of the Minnesota GOP called for the president's resignation.
"I’m a lifelong Republican and I’m calling for the immediate resignation of [President Donald Trump," Aplikowski tweeted.
"Get the f*** out of the White House, Republican Party, and Washington and take your anarchist rioters with you."
His colleague, Minnesota GOP chair Jennifer Carnahan, called for a peaceful resolution in D.C.
"The violence taking place at the US Capitol is not American or representative of what we believe in, in our country," she tweeted.
"Peaceful protests are one thing, but attacking police and breaking into the Capitol is quite another. Hoping for peace and the safety of all."
A rally, so far peaceful, is being held outside the Minnesota Capitol, but there have been comments made by some of the speakers that could be considered threats towards, among others, Gov. Tim Walz.
