On May 24, 2018, the American Civil Liberties Union of Texas and the Texas Civil Rights Project filed an amicus brief in support of a motion for a new trial in Texas v. Mason. The defendant in that case, Crystal Mason, was criminally prosecuted and sentenced to five years in prison for allegedly casting a provisional ballot improperly.
There is no evidence of widespread voting fraud in the United States. Recently, the Fifth Circuit Court of Appeals found only two cases of in-person voter fraud out of 20 million votes cast. The case is currently pending ruling on defendant's amended motion for new trial.
