Former presidential candidate and U.S. senator John Edwards is asking for a 60 day delay on his criminal trial, citing an unexpected medical issue.

Yesterday Edwards’ lawyers filed the motion, hoping to delay the January 30 start date for his trial stemming from charges by the Justice Department which include conspiracy, issuing false statements and violating campaign contribution laws.

Edwards’ medical condition was not disclosed, but details were provided in a sealed attachment to the motion.

He’s accused of using about $1 million in undisclosed payments from campaign donors to cover up an affair with campaign videographer Rielle Hunter during his 2008 White House bid. He has pleaded not guilty.

Edwards’ wife Elizabeth died from Cancer last December. In September, his trial was delayed to January 30, when his attorney said he needed more time, citing his role as a sole caretaker of his two youngest children.

If convicted on all counts, Edwards could face 30 years in prison and a fine of up to $1.5 million.
