Republicans fighting an earmark ban "didn't get the message" from last week's election, a House conservative said Tuesday evening.

Rep. Jeff Flake (R-Ariz.), a longtime foe of earmarks, seemed to take aim at Senate Minority Leader Mitch McConnell (R-Ky.) over a report that the GOP leader was fighting an earmark moratorium that's been proposed in the Senate.

Flake tweeted:

Looks like someone didn't get the message last week...

Republicans in the Senate are set to battle internally next week over a proposed two-year moratorium on earmarks, the practice by which a lawmaker can direct spending to a particular project.

Sen. Jim DeMint (R-S.C.) is leading 10 other Republicans, including some senators-elect, in pushing for a vote on a moratorium among Senate Republicans. The push by DeMint is seen as a key test of his newfound influence against McConnell, who's perceived as more resistant to an outright ban on earmarking.

House Republicans have already passed a moratorium on earmarks (over the objections of some members), which leaders have suggested will continue for the next two years.
