When a crash victim’s mother said during a bond hearing that state Sen. Paul Campbell’s actions could have killed her daughter, the lawmaker cracked a smile, a video of the proceeding showed.

Campbell, chairman of the Senate Ethics Committee and chief executive of the Charleston County Aviation Authority, is accused of driving drunk Saturday night when his car rear-ended another on Interstate 26 near Goose Creek.

No one was seriously injured, but Campbell’s alleged handling of the episode prompted some observers on Monday to call for his resignation. Others, including airport officials, said the Goose Creek Republican first deserves a fair chance to prove the innocence he has professed.

Meanwhile, Charleston-area prosecutors with close ties to Campbell cited a possible conflict of interest and forwarded the case to the S.C. Attorney General’s Office for review.
