Rep. Tim Huelskamp (R-KS) said this week that he will join efforts to impeach of Attorney General Eric Holder over his stance on marriage equality, citing a petition by the Coalition of African-American Pastors and accusing Holder of trying to “thwart” the Constitution by not defending the Defense of Marriage Act.

Of course, the Obama administration would be far from the first administration to decline to defend an unconstitutional law, with Republicans and Democrats alike doing the same in the past.

Several Republicans have already proposed a resolution seeking Holder’s impeachment.
