Democrats are blocking Republicans from sending out mailer

Democrats are preventing Republican House Members from sending their constituents a mailing that is critical of the majority’s health care reform plan, blocking the mailing by alleging that it is inaccurate.

House Republicans are crying foul and claiming that the Democrats are using their majority to prevent GOP Members from communicating with their constituents.

How can this possibly be legal? President Obama got an hour of free air time last night to peddle his crap. Surely, the Republicans send out a mailer countering Obama's claims.
