Missouri's most prolific political financier gave nearly $1.3 million to various political causes in the closing weeks of 2013.
Online state campaign finance reports show that retired investment firm executive Rex Sinquefield gave $750,000 to Teachgreat.org, $495,000 to Grow Missouri and $25,000 to Missourians for Excellence in Government during the final weeks of December.
Teachgreat.org is backing a potential ballot initiative that would end tenure protections for public school teachers and instead make their employment contingent on student achievement.
Grow Missouri is backing a potential ballot initiative that would cut Missouri's income tax rates.
Missourians for Excellence in Government is a political action committee that has funded candidates, most notably St. Louis Mayor Francis Slay.
Online records show Sinquefield gave more than $3.8 million in Missouri political contributions in 2013.
