Second Crossover marks the beginning of what we call Conferencing here at the State Legislature.
On the 50th day of session, the Senate President and House Speaker create a list of "conferees" who will be appointed to specific bills. A conference committee is comprised of members of both the House and Senate whose sole purpose is to work out differences between the respective bill drafts.
To assist the standing committees and Senate conferees, Senate Majority Research (SMA) creates comparison sheets of the Senate bills that set out the differences between the House and Senate drafts in conference.
At this point, the Senate and House standing committees (i.e. Senate Committee on Intergovernmental Affairs) are pretty much dissolved. Public testimony is no longer accepted, although letters and calls are still encouraged.
