Some school districts are refusing to show President Obama's speech to their classes on Tuesday.

The president's back-to-school talk will be broadcast live over the Internet to classrooms across the country.

Some parents fear the president will try to indoctrinate their children. They point to the original wording of the speech which called on students to "Help the president."

But over the weekend, the White House went on the offensive, calling such concerns silly.

Sen. Lamar Alexander, R-Tenn., the former education secretary for President George H.W. Bush, who also spoke to students said schools should use the speech as an opportunity.

"If I were a teacher, I'd take advantage of it," he said. "And I'd put up Lincoln and Eisenhower and Reagan and teach about the presidency."

The administration will post a text of the speech on the White House website Monday.
