Judge urges jurors to keep deliberating.

There's been no verdict and no mistrial after five days of deliberations in former Minnesota Gov. Jesse Ventura's defamation lawsuit against "American Sniper" author Chris Kyle.

Deliberations are to resume at 9 a.m. Tuesday, a day after jurors told federal Judge Richard Kyle they didn't think they could reach a unanimous verdict. The judge urged them to keep trying.

Jurors continued deliberating roughly four more hours Monday before calling it a day. Their discussions since last Tuesday have now topped 31 hours.

Chris Kyle wrote in his best-seller that he decked Ventura in a California bar in 2006 after Ventura allegedly said Navy SEALs "deserve to lose a few." Ventura, a former SEAL and pro wrestler, testified Kyle fabricated the story. Kyle denied that in testimony videotaped before his death last year.
