PORTLAND – Maine Sen. Susan Collins has introduced a measure to beef up homeland security by requiring the federal government to provide a security adviser for Maine and nine other states that don’t have one.

Supporters include New Hampshire Sens. Judd Gregg and John Sununu.

Gregg said the advisers are specially trained to respond to a variety of emergency situations and that it is important for each state to have one.

Besides Maine, the bill would require advisers for New Hampshire, Vermont, Rhode Island, Delaware, North Dakota, Wyoming, South Dakota, Montana and Idaho.
