Our work to hold Congress accountable only matters if elections are decided by counting votes. After the 2020 Presidential Election, President Trump, his advisors and associates, and Republican legislators collaborated in a failed coup to have the election decided by themselves rather than by voters.
Mast was among the Republican legislators who participated in this. On January 6, 2021 in the hours after the violent insurrection at the Capitol, Mastvoted to omit Arizona and/or Pennsylvania from the counting of presidential electors, whichcould have altered the outcome of the election in Trump’s favor.
In 2023, Trump associates and top advisors pleaded guilty tosubmitting a fraudulent slate of electors to Congress from Georgia,making false statements about purported widespread fraud in the election, andtampering with voting machines after the election, admitted in civil court toposing as fake electors in Wisconsin, and were convicted ofcontempt of Congress for withholding documents during its investigation andassaulting police officers at the Capitol. Trump associates and top advisors are also currently facing charges for submitting fraudulent slates of electors to Congress inMichigan,Nevada,Arizona, andWisconsin. Trump himself facesrelated criminal charges in state court, and a federal investigation which terminated because he won re-election alleged thatTrump sought to ignore true vote counts, manufactured fraudulent slates of presidential electors, and used the January 6 riot to obstruct the congressional certification of the presidential election. Trump was impeached but not convicted in 2021 for incitement of insurrection related to the same events. (He was also impeached but not convicted of using the presidency to solicit the help of a foreign government to benefit his reelection in 2019, and he wasconvicted in state court in 2024 for falsifying business records to cover up acts that he believed might have hurt him in the 2016 election.) TheJanuary 6, 2021 violent insurrection at the Capitol,led on the front lines by militant white supremacy groups one member of which wasconvicted of sedition, attempted to prevent President-elect Joe Biden from taking office by disrupting Congress’s count of electors.

Does 6 not sound like a lot? Very few bills are ever enacted — most legislators sponsor only a handful that are signed into law. But there are other legislative activities that we don’t track that are also important, including offering amendments, committee work and oversight of the other branches, and constituent services.
We consider a bill enacted if one of the following is true: a) it is enacted itself, b) it has a companion bill in the other chamber (as identified by Congress) which was enacted, or c) if at least about half of its provisions were incorporated into bills that were enacted (as determined by an automated text analysis, applicable beginning with bills in the 110th Congress).
