Alleged priest abuse victim's father-in-law testifies

Donald McGuire is accused of traveling outside the U.S. and across state lines to have sex with a teenager between 2000 and 2003.

The father-in-law of the alleged victim says his son-in-law has trouble telling the truth. Under cross examination, he admitted his opinion was based on family situations and not the sex abuse case.

McGuire was convicted of child molestation in Wisconsin in 2006 and sentenced to seven years in prison.
