This is a summary of recent congressional actions not reported elsewhere in The Post. HOUSE Liberian Aid

The Foreign Affairs Committee approved, by voice vote, a nonbinding resolution calling for suspension of $13 million in military aid to Liberia until that country holds "free and fair" elections. The West African nation's Oct. 15 presidential election was deemed unfair by international observers. Similar legislation was passed by the Senate. The $13 million in military aid is part of a $91 million aid package that the United States was scheduled to send to Liberia in fiscal 1986. (No bill number; Jan. 29) Hydroelectric Relicensing

An Energy Conservation and Power subcommittee unanimously approved a bill that would eliminate the municipal preference in the relicensing of hydroelectric projects. In addition, the measure would give the U.S. Fish and Wildlife Service, the National Marine Fisheries Service and state wildlife agencies the right to recommend conditions for licenses. (HR44, Jan. 29) Protection for Mentally Ill

The House approved, 290 to 84, legislation authorizing a three-year program to help states establish protection and advocacy systems for the mentally ill. States would be required to certify that they have, or will establish, such a program in order to receive Alcohol, Drug Abuse, and Mental Health Administration block grants. The bill also requires that the Department of Health and Human Services promote the establishment of family support groups within medical and health research facilities to help individuals with Alzheimer's disease, and their families. Similar legislation has been approved by the Senate. The measure authorizes $10.5 million in fiscal 1986, $11 million in fiscal 1987 and $11.5 million in fiscal 1988. Those monies have been approved in a separate appropriations bill. (HR4055, Jan. 30)
