Historian Eric Foner was among the first to suggest using it and he later wrote up his argument in the WaPo here: https://www.washingtonpost.com/outlook/2021/01/12/14th-amendment-impeachment-alternative/
Two legal scholars, Gerald Magliocca and Bruce Ackerman also argued that using section 3 may be more effective than impeachment: https://www.washingtonpost.com/opinions/2021/01/11/impeachment-wont-keep-trump-running-again-heres-better-way/
In the @nytimes, @brianbeutler and @deepakguptalaw say it section 3 should be used as a compliment to impeachment. https://www.nytimes.com/2021/01/12/opinion/Trump-impeachment-disqualification.html?smtyp=cur&smid=tw-nytopinion
Political scientist and professor of law Mark Graber makes the case that section 3 can be invoked by legislation passed after Trump leaves office, which would also "retroactively void any action taken by President Trump after January 6, 2021." https://theconstitutionalist.org/2021/01/11/section-three-to-the-rescue-by-mark-graber/
Law professor Noah Feldman argues that a court could determine Trump violated section 3 were he to attempt another presidential bid in 2024: https://www.bloomberg.com/opinion/articles/2021-01-11/trump-2024-president-may-be-ineligible-after-u-s-capitol-riot
Several folks have argued against using section 3. Political scientist @kewhittington argues impeachment is the correct remedy and "If Section Three is to be applied, then it should follow a criminal conviction for engaging in an insurrection" https://reason.com/volokh/2021/01/13/the-14th-amendment-disqualification-gambit/?utm_source=dlvr.it&utm_medium=twitter
Law professor David Hemel argues "A better approach would be for Congress to enact a modern-day analogue to the First Ku Klux Klan Act reestablishing a judicial procedure to disqualify insurrectionists," though that can work alongside impeachment. https://www.washingtonpost.com/outlook/2021/01/12/14th-amendment-insurrection-trump-removal-problems/
In an argument against creatively using the Constitution, Historian @DavidHeadPhd argues that "Removing a president from office is novel enough" and "Congress should embrace its experience with impeachment and devote its energy to that path alone." https://thebulwark.com/the-14th-amendment-is-not-an-alternative-to-impeachment/
