Lawmakers began arriving at the Capitol for the start of a legislative session in which they're expected to consider tax reforms and to search for ways to shore up the financially troubled pension system for government retirees this morning.

A task force appointed by Gov. Steve Beshear has recommended a series of changes to the state tax code that could generate more than $600 million in additional revenue. And a separate legislative task force has recommended pumping more money into the pension system, which has a $33 billion unfunded liability.

Beshear has said he's not sure lawmakers can resolve those issues in the 30 days allotted for the session. If not, he could call a special session later.
