Palin's past praise for Trooper Wooten

From NBC's Jim Popkin
Years before "Troopergate" and accusations that Alaska Gov. Sarah Palin tried to kick her former brother-in-law out of the state police force, she was praising him as "a fine example" of "high-caliber personnel." In a letter dated July 8, 1999, Sarah Palin commended her future brother-in-law, Mike Wooten, for his hard work at Wasilla's July 4th parade.

"SRA Wooten worked hard to locate and deliver appropriate supplies to use in our parade," the then-mayor of Wasilla wrote to Wooten's Air Force commander. "I believe Mike is a fine example of the high-caliber personnel we are blessed to have in the United States Air Force.
