Jena Griswold filed a brief ahead of oral arguments next week considering whether Trump can be barred from office for his efforts to overturn the 2020 election.

Colorado Secretary of State Jena Griswold asked the Supreme Court on Wednesday to conclude that the state can lawfully bar former President Donald Trump from the Republican primary ballot because of his actions in 2020 that culminated in the Jan. 6 attack on the Capitol.

The case concerns, among other things, whether Trump “engaged in insurrection” under Section 3 of the Constitution’s 14th Amendment and is therefore prohibited from serving as president.

Griswold, a Democrat who is the top election official in the state, filed a brief ahead of Supreme Court arguments next week that defended Colorado’s process for determining whether candidates are eligible.
