==History==
On 10 December 2019, the [[Superior Electoral Court]] considered valid the repeal of senator Selma Arruda term, along with her substitutes, elect in 2018. The former judge was accused of omitting expenses of [[Brazilian real|R$]] 1.2 million ([[United States dollar|US$]] {{formatnum:{{To USD|1200000|BRA|year=2018}}}}, as of 2018) in her electoral campaign to fill one of the two seats available and represent the state of Mato Grosso in the Senate, configuring supposed [[slush fund]]s and abuse of economic power. It is necessary a bureaucratic act from the Senate Director Board to fulfill this decision. Selma Arruda could appeal to the [[Supreme Federal Court]], but the appeal, at first, cannot suspend the TSE decision.<ref>{{cite web|url=https://g1.globo.com/politica/blog/matheus-leitao/post/2020/01/08/alcolumbre-deve-dar-prosseguimento-a-cassacao-da-senadora-selma-arruda-apos-fim-do-recesso.ghtml|title=Alcolumbre deve dar prosseguimento à cassação da senadora Selma Arruda após fim do recesso|publisher=G1|language=pt|first=Matheus|last=Leitão|date=8 January 2020|accessdate=15 February 2020}}</ref>
