In an effort to counteract the Supreme Court's decision on Citizens United -- the law that opened the door to free-flowing outside money -- Congress has introduced the Disclose Act, first in 2010 and again in 2012, to require all groups that donate more than $10,000 in political spending to disclose their donors.
On Wednesday, at a Senate Rules Committee hearing, Senate Minority Leader laid out his opposition to the bill.
"Sadly, it's now come to the point where you can set your clock to the Democrats' attempt to stifle the free speech rights of the American people," Sen. Mitch McConnell, R-Ky., said. "The entire premise for it is utterly baseless."
McConnell sees the bill as a violation of the First Amendment. Congressional Democrats, however, see this bill as a way to hold big donors accountable for secret spending and influencing voters.
"The result is an almost total loss of accountability," Sen. Angus King, I-Maine, explained to the Committee. "The hiding of vital information from voters, who it is that's trying to influence their votes, and an inevitable slide towards corruption and scandal."
"Let me be blunt — this proposal is nothing more than a crude intimidation tactic masquerading as good government," said McConnell.
The 2014 version of this bill, introduced by Sen. Sheldon Whitehouse, D-R.I., is currently co-sponsored by 50 senators, all of whom are Democrats.
