PORTLAND — A young Somali-American man convicted of plotting to bomb a 2010 Christmas tree-lighting ceremony in Portland’s town square has written an apology letter in advance of his sentencing.

In a letter from jail, filed by his lawyers in federal court, Mohamed Mohamud offers to speak to young Muslims “to help keep them away from the path of extremism.” And he told U.S. District Judge Garr King he turned to books to help him “walk a better path.”
