John W. Carroll appeals the district court's order and judgment that denied him relief on Carroll's race discrimination and retaliation claims following trial. Having reviewed the record and the parties' briefs, we conclude Carroll is not entitled to relief. We further conclude the district court's fact-findings are not clearly erroneous and no error of law appears. Because the controlling law is clear and an opinion would have no precedential value, we affirm the judgment of the district court without further discussion. See 8th Cir. R. 47B.
