House Minority Leader John Boehner (R-Ohio) has pledged to contribute $1 million to congressional Republicans' campaign efforts this fall.

Boehner pledged the hefty sum as part of the National Republican Congressional Committee's (NRCC) "Battleground" effort, a push beginning this week to cull $20 million from sitting GOP lawmakers to help elect more Republicans this fall.

The money will come from Boehner's campaign account, and will be on top of the $755,000 he's already contributed to the committee, and in addition to the $30,000 from his PAC.

Boehner's contribution could be seen as setting an example for rank-and-file members to pony up for this fall's midterm efforts.

The top House Republican has said Republicans could compete in as many as 100 congressional districts this November, and the NRCC's support could be key in converting many of those opportunities.
