Actress, singer and Al Sharpton supporter Barbara Streisand is, in one fell swoop, distancing herself from the upcoming CBS "biopic" about Ronald and Nancy Reagan, and defending it.

In a "truth alert" posted to her web site yesterday, Streisand said she never saw the script for the project in which her husband, James Brolin, plays Ronald Reagan. She said she only appeared on the production set one day, for four hours. But that didn't stop her from defending the movie, which Reagan supporters criticize and being unfair, inaccurate and distorted:

What is going on instead is that the Republicans, who deify President Reagan, cannot stand that some of the more unpleasant truths about his character and presidency might be depicted in the movie, along with his positive actions...

She also addressed those who have said the project is a CBS-run smear campaign and a last-ditch attempt to tar the 40th president's legacy.

Says Streisand:

This is what the Right Wing does when they are faced with a truth that is not 100% positive for their side - they spread vicious lies and attacks and scream and yell until they get their way.

We reported last week that Streisand contributed $1,000 to the presidential campaign of Rev. Al Sharpton, who rose to prominence in the late 1980s by helping to advocate the Tawana Brawley hoax in the Hudson Valley.
