A member of the San Joaquin Valley Air Pollution Control District says he's sorry for saying he "tunes out" environmentalists at air quality meetings.
Merced County Supervisor Mike Nelson, inset, says he won't step down from the board, as about 100 air quality advocates picketing the board meeting Thursday demanded.
Among those asking for his resignation was Dolores Huerta, co-founder of the United Farm Workers. Nelson said he meant no offense and was trying to encourage people to work together.
State Senate Majority Leader Dean Florez sent Nelson a letter this month saying the remarks created an "unwarranted level of hostility."
