Throughout the past several decades, the release of a NIE on a controversial policy have usually resulted in charges that the IC politicized its key findings. Charges of politicization come from both Democrats and Republicans, but normally emerge from the side that does not agree with the policy implications of the analysis. Changes or reversals in NIE assessments over time cause some legislators to question whether the change resulted from newly collected intelligence or whether analysts changed their position to support a specific political agenda.
