As leaders of several of the largest cities in the United States vow to defy federal immigration law to shield illegal immigrants from deportation, country legend Charlie Daniels has suggested a similar idea for pro-life cities across the country: namely, that they ignore federal abortion law and become “sanctuary cities” for unborn children.

The 80-year-old Grammy-winner made the suggestion in a post to his Twitter account early Thursday morning.

“How about some cities declaring themselves a sanctuary for the unborn and refuse to abide by the federal laws allowing abortion,” Daniels wrote.

Daniels’ suggestion comes as the Center for Medical Progress released a new undercover video this week that revealed additional details behind the abortion process at Planned Parenthood, the country’s largest abortion provider. Earlier this week, California prosecutors charged CMP staffers with a slew of felonies for recording Planned Parenthood staff without their consent.

Daniels — set to release a book of memoirs in October — has kept up his political activism in recent months.

“Unfortunately I feel the ebb of patriotism again. I can’t believe that we have set back in this country and let things deteriorate to the point that they are,” he told Daniel Defense in an interview. “And I cannot believe how very unaware about 40 percent of the population of this country are about what is happening.”
