It started as a small Facebook event, but hundreds met at the Islamic Center of Maine on Friday, putting pen to paper and writing to members of Maine's delegation.
They wrote letters to Sen. Susan Collins, Sen. Angus King and Rep. Bruce Poliquin, hoping the lawmakers will fight the executive order.
"They need to ease our fears and help us be courageous, not terrify us," says Thomas Griffith.
Those at the mosque say they've seen an outpouring of support and are reaching out to others.
"You should take the time to go to a mosque to learn about the community, meet the people before you make a decision that all Muslims should be banned," says Kelly Darwish.
They also said it's heartwarming to see the amount of people who met to write letters.
