AUGUSTA — Phil and Sarah Groman traveled from Union to the capital Saturday to stand with about 200 supporters of the Affordable Care Act.

While they don’t get their health insurance through the program, they have a 27-year-old son with a pre-existing condition who does.

Without the Affordable Care Act, Phil Groman said, his son likely wouldn’t have insurance.

The Gromans weren’t among those carrying signs, but they were among the people across the country who were expected to turn out at rallies Saturday in a show of support for former President Obama’s law that expanded by millions the number of those insured in the United States.

President Trump campaigned on a promise to immediately repeal and replace the law known as Obamacare. Shortly after he took office, Trump signed an executive order intended to ease the path for repealing the act. The Republican-led Congress is considering options to replace the program. Sen. Susan Collins, R-Maine, has collaborated on a plan that would let individual states keep the health insurance exchanges created under the law if they wish.

In Maine, about 80,000 have gained coverage under the Affordable Care Act. About 20 million are covered nationwide.

Augusta Mayor David Rollins and Gardiner Mayor Thom Harnett also attended the rally.
