JUNEAU -- Alaska's governor has proclaimed Saturday a day of prayer for the nation, heeding a call from Texas Gov. Rick Perry.

Gov. Sean Parnell cites Perry in the proclamation. Perry, who's considering seeking the Republican nomination for president, invited fellow governors to join him at a prayer event in Houston, Texas, Saturday. He also urged them to proclaim Aug. 6 a time to pray for "unity and righteousness." Parnell's spokeswoman said Parnell won't attend but issued a proclamation recognizing "we are a nation under trial of war, impacts of natural disaster, threat of more severe economic hardships, and that our families are under attack on many fronts."
