WASHINGTON -- The Supreme Court is set to decide soon on the fate of President Barak Obama's health care law.
And as the ruling looms, "Obamacare" opponents plan to gather nationwide Friday in protest.
In March, more than 60,000 protestors came together in 145 cities and communities to protest mandates in the health care law that will require employers, including religious groups, to offer access to free contraception, including Plan B.
"This is the most dangerous and egregious attack on religious freedom in the history of the United States," Pat Mahoney, with the Christian Defense Coalition, said.
This month, 155 cities are expected to participate in the "Stand Up" rallies sponsored by the Stand Up for Religious Freedom Rallies Coalition.
"We've heard a lot about this mandate and there has been a lot of spin coming from the White House and a lot of misinformation from the mainstream media," the group's co-director, Eric Scheidler, told CBN News.

Lila Rose, president of the Live Action group known for exposing Planned Parenthood activities, has been outspoken on the issue.
"Our liberties are under attack right now," she said. "Our religious freedom is under attack right now, and taking that stand is essential."
Rob Schenck, president of the Christian government outreach group Faith and Action, is working at the highest levels to fight the birth control mandate. He recently met with Pope Benedict XVI's personal ambassador to the U.S.
"We talked at great length about the necessary alliance between evangelicals and Catholics," Schenck said. "And I have never sensed a closer bond with our Catholic friends than over this issue."
Friday rallies were deliberately set on the 223rd anniversary of Founding Father James Madison introducing the Bill of Rights, which begins with the guarantee of religious liberty.
"We do have a concept of proper separation of church and state," Schenck explained. "In this instance, the president of the United States has said, 'I will tell you how you will practice your religion.' That is outrageous."
"It's insanity what the administration is pushing on the Catholic church, pro-life people, Catholics," Rose added.
She said she sees a thread going right from legalized abortion to the present threat against religious liberty.
"Americans in increasing numbers are agreeing that ... people should be able to be born ... They should be able to live," Rose said.
"If we allow that fundamental attack on the unborn child ... that fundamental attack on the most basic human right [of] life, we should not be so surprised when they come for our religious liberty," she continued.
Mahoney equates the birth control mandate to telling Christian institutions that "we could not pray in the name of Jesus, or we could not read the Bible."
"And this is an egregious violation of the First Amendment, a flagrant violation of the First Amendment," Schenck added.
Protestors want the nation to realize if the government doesn't respect human life, it won't respect your liberty either.
