A bill U.S Sen. Amy Klobuchar wrote to help recover missing and exploited children is on the presidents' desk to be signed into law.

"As a former prosecutor, I know that returning missing children to their families is one of the most important tasks law enforcement officers have, and they need every tool available to track these children down and bring criminals to justice," the Minnesota Democrat said.

About 200,000 American children are abducted by family members each year.

The tax-collecting Internal Revenue Service has addresses for many of them, and Klobuchar's bill forces the IRS to provide them to official investigators in missing-children cases.
