Anti-gun US Rep. Michael Grimm (R-NY), who pleaded guilty last week to a single federal felony tax evasion charge stemming from his falsified business tax return, will resign his Congressional seat on Jan. 5 “because he does not feel he can be completely effective in Congress.” Grimm had said earlier that he would not resign.

As part of a plea deal for one count of aiding in the filing of a false tax return, Grimm, a 44-year-old former Marine and FBI agent, also signed a statement admitting to concealing over $900,000 in receipts from 2007 to 2010 and lying during a 2013 deposition. Grimm was indicted on 20 counts. The case grew out of an investigation into Grimm’s campaign finances which resulted in no other charges, but a woman romantically linked to him pleaded guilty in September to lining up straw donors for his 2010 run. Grimm faces a maximum of three years in prison.

House Speaker John Boehner (RINO-OH) had not publicly called for Grimm’s resignation and could not have prevented Grimm from being sworn in next month, but could ask the Ethics Committee for his expulsion, or presumably initiate Articles of Impeachment. But Boehner won’t even try to impeach felonious Democrats such as Eric Holder and Barack Obama. Under House rules, a member convicted of a crime punishable by more than two years in prison is instructed not to participate in committee work or even to vote on the House floor “until the member is re-elected to the House after the date of such conviction.” In other words, Congressmen can be felons (duh), and still not be automatically expelled.
