CABRERA: Tens of thousands of people hit the streets of Dallas today. A massive gathering, organizers called peaceful but this was an urgent call to bring change for those people who are out there. They want their voices heard when it comes to immigration and racial equality. CNN's Ed Lavandera was there -- Ed.</s>ED LAVANDERA, CNN CORRESPONDENT: Ana, on the streets of downtown Dallas this afternoon tens of thousands of protesters turning out to march in what has been billed as Mega March 2017. Tens of thousands of people have been winding their way, this is a marching route that is now spanning several miles here through -- the streets of downtown Dallas, making its way from the Cathedral in downtown here to the steps of city hall. This is a pro-immigration rally, calling out what they view as the abusive policies of Donald Trump. That is what you see repeatedly from here, not just on questions of immigration, but at how undocumented migrants are being treated currently by this administration. So you this repeated. Dr. Martin Luther King III was one of the lead marchers here as well as a number of civil rights activists, and joined by a great number of Democratic Party leaders here in the state of Texas as well. A similar rally was held back in 2006 where hundreds of thousands of people turned out. They're doing it once again this time. And this is a crowd that has grown to massive numbers here this afternoon in the streets of downtown Dallas -- Ana.</s>CABRERA: Ed Lavandera, thank you. Straight ahead tonight, police are keeping a close eye on churches in Wisconsin on this Palm Sunday after an online threat is made, aimed at President Trump. The latest on the manhunt to find this suspect. You are live in the CNN NEWSROOM.
