Willie Nelson will perform on Saturday morning at a voting rights rally at the Capitol in Austin. Nelson's appearance will wrap up a four-day voting rights march that started on Wednesday morning in Georgetown. Rev. Jesse Jackson joined the march on Thursday morning in Round Rock. The march will end at the Capitol with a rally scheduled to start at 10 a.m. Saturday. Participants are supporting the efforts of Texas Democrats who fled the state for Washington, DC, in order to obstruct passage of an election integrity bill.
