In March 2010, President Obama and Stupak reached an understanding whereby the President promised to sign an Executive Order barring federal funding of abortion through the Patient Protection and Affordable Care Act, and Stupak and several of his allies promised to withdraw their opposition to the bill. The Pro-life movement accused Stupak of betraying their movement, and the pro-life Susan B. Anthony List revoked an award it had planned to give to him and instead ran $150,000 worth of radio advertisements against him. Stupak was targeted by the Tea Party movement in the wake of his compromise. In April 2010, Stupak announced his intention to retire from Congress, leading conservative groups to point to the political consequences of his compromise as a possible reason for his decision. However, Stupak himself attributed his retirement to the exertion of constant travel back and forth from Washington, D.C.
