Rep. G.K. ButterfieldG.K. ButterfieldFCC defends not fighting legal challenge to prison call rates A guide to the committees: House 40 House Dems to urge Trump to suspend Flynn MORE (D-N.C.) said the voter-ID laws are a Republican response to President Obama's election.

"Is this a serious voter problem? No," he said. "Unfortunately, it is a cynical and malicious Republican attempt to suppress minority and elderly voters who turned out in historical numbers for the '08 elections."

Others said the laws are akin to a poll tax, something used more than 100 years ago in an effort to discourage minority voters. The lawmakers said the requirement of an official government identification is a cost that many cannot afford, and which interferes with their right to vote.

Rep. John Lewis (D-Ga.), a civil-rights activist in the 1960s, spoke along with other Democrats and warned that these state laws must be rejected.

"We must fight back," he said. "We must speak up and speak out. We must never, ever go back. We will not stand idly by while millions of Americans are denied their right to participate in the democratic process."

Republicans did not mount a rhetorical defense of voter ID laws on the floor Tuesday, although some have supported these laws as a way of ensuring that only legal U.S. citizens vote at the polls.
