During the trial in January 2020, the House impeachment managers presented their case for three days. They cited evidence to support charges of abuse of power and obstruction of Congress and asserted that Trump's actions were exactly what the founding fathers had in mind when they created the Constitution's impeachment process.<ref>{{cite news|url=https://www.washingtonpost.com/politics/democrats-detail-abuse-of-power-charge-against-trump-as-republicans-complain-of-repetitive-arguments/2020/01/23/3fb149b4-3e05-11ea-8872-5df698785a4e_story.html|title=Democrats detail abuse-of-power charge against Trump as Republicans complain of repetitive arguments|date=January 23, 2020|newspaper=[[The Washington Post]]|access-date=January 27, 2020|first1=Seung Min|last1=Kim|author-link1=Seung Min Kim|first2=John|last2=Wagner|first3=Karoun|last3=Demirjian|author-link3=Karoun Demirjian}}</ref>
