WASHINGTON D.C. -- Groups of pro-life Michiganders from across the state are in Washington D.C. today for the anti-abortion March for Life.

Right to Life of Michigan affiliates organized 16 buses to ferry marchers to the nation's capital, according to a press release from the organization.

Chris Gast, its director of communication and education, said another three buses carried 150 Michigan college students to the march.

"Some of us are already here," Gast said. "Some of us are just arriving.

"I think everyone is excited about the energy."

He said the group hopes to send a message to the nation's leaders, particularly the U.S. Supreme Court. They need to know a vocal group still opposes the court's landmark 1973 decisions on abortion, Gast said, referencing Roe v. Wade and Doe v. Bolton.

"We're here and we're just not going to accept the injustice of those two Supreme Court decisions," he said.

Gast said the group from Michigan are excited for the march on the National Mall and speeches by U.S. Speaker of the House Paul Ryan and others.

"The pro-lifers are here and there are a lot of us," he said.
