Frances and Efrain Santiago, natives of Puerto Rico, wanted to show their support last month for protesters back home seeking to oust the island's governor.
The couple flew the flag of Puerto Rico on the garage of their Kissimmee home. It ticked off the homeowners association.
Someone from the Rolling Hills Estates Homeowners Association left a letter at their home, citing a "flag violation" and warning: "Please rectify the listed violation or you may incur a fine."
Frances Santiago, 38, an Army veteran, demanded to know why.
