COLUMBIA--Campaign donors and political parties will face greater scrutiny under campaign finance reform legislation signed into law Thursday by Gov. Mark Sanford.

Under the new law, political parties must disclose soft money contributions; political action committees will be unable to transfer money for state campaigns among themselves; and lobbyists will face more restrictions on donations.

Lawmakers have been working on campaign finance bills for years, but their efforts typically have stalled in the Senate. Former Gov. Jim Hodges vetoed similar legislation in November 2000, saying it was unconstitutional.
