Protesters backing Guatemalan President Otto Perez Molina are blocking access to Congress where lawmakers are scheduled to consider a move to withdraw his immunity from prosecution in a widening corruption scandal.

A number of other people have formed a human chain to try to help legislators enter the building in the Central American nation's capital.

Prosecutors were seeking an order Tuesday for police to remove the demonstrators so deliberations could begin.

The congressional process against Perez Molina is akin to impeachment and could lead to criminal charges.

A commission of lawmakers already has recommended Perez Molina's immunity of office be withdrawn. Now the issue is before the full Congress.
