Senate panel members backtracking on votes to support rate hikes in subsidized federal flood insurance program.
Hearing Wednesday focuses on affordability issues in National Flood Insurance Program rate hikes coming in October.
Rates to sharply increase after Oct. 1, while Louisiana lawmakers cry foul.
Louisiana insurance chief says 2014 NFIP rate increase would raise rates for "working coast" beyond affordability.
Congress is currently deflecting intense pressure to roll back virtually all the increases in flood insurance premiums imposed in 2012.
Amendment passed Tuesday would bar the rate increases by preventing FEMA from using federal funds to implement Sec. 207.
The amendment passed 281-146, and the appropriations bill was later approved by the full House and sent to the Senate.
