JEFFERSON CITY, MO. -- Missouri senators overwhelmingly passed a bill revising a new law that restricts teachers' online conversations with students.

The legislation would repeal a law barring teachers from using websites that give "exclusive access" to students, such as sending private messages on Facebook.

Senators voted 33-0 Wednesday to send the bill to the House.

The provision had already been temporarily blocked by a judge last month because of free-speech concerns.

Governor Jay Nixon asked lawmakers to repeal the measure during a special legislative session. The Missouri Senate is going a step further by replacing the current law with a new one that will require school districts to come up with policies on employee-student communications by March 1^st.

The bill needs a second Senate vote before it can move over to the House.
