Bill Haslam, Tennessee Governor, Urged To Veto Controversial 'Monkey Bill'

Gov. Bill Haslam (R-Tenn.) is facing a new round of pressure this week to veto controversial legislation that critics argue would open the floodgates to anti-science teaching in the state's public schools.

SB 893 -- known as the "Monkey Bill" by opponents who claim it's an anti-evolution bill that pays homage to the Scopes Trial-era -- is designed to protect teachers who allow students to question and criticize "controversial" scientific debates on topics such as evolution, climate change and human cloning. Haslam has said that he'll "probably" sign the bill after downplaying the opposition's concerns, but now he's hearing a chorus of complaints from across the state.

On Thursday, Haslam received a letter and petition with 3,200 signatures urging him to veto the "dangerous" measure.

"We believe this bill will send the wrong message to children," said Mina Johnson, one of the petitioners. "And also, as if, this bill will disguise denying otherwise scientifically proven fact."

Americans United for Separation of Church and State and the American Civil Liberties Union have also pressured Haslam to reject the bill, which they believe is an unconstitutional and unwise gateway for the teaching of creationism and intelligent design in public schools.

Hedy Weinberg, executive director of the American Civil Liberties Union of Tennessee, told the Wall Street Journal that the measure contained "very clever" wording designed to quietly "inject religious beliefs into scientific curriculum."

Proponents, however, have maintained that it's simply meant to encourage a diversity of opinions in the classroom.

"The idea behind this bill is that students should be encouraged to challenge current scientific thought and theory," said GOP state Sen. Bo Watson, the measure's sponsor, last month.

"Global warming, evolution, these can be controversial," Republican state Rep. Bill Dunn told the Wall Street Journal.

Haslam has until Tuesday to sign the bill, veto it, or allow it to become law without his signature.
