The White House Press Office has refused to give the Boston Herald full access to President Obama's Boston fund-raiser today, in e-mails objecting to the newspaper's front page placement of a Mitt Romney op-ed, saying pool reporters are chosen based on whether they cover the news "fairly."

"I tend to consider the degree to which papers have demonstrated to covering the White House regularly and fairly in determining local pool reporters," White House spokesman Matt Lehrich wrote in response to a Herald request for full access to the presidential visit.

"My point about the op-ed was not that you ran it but that it was the full front page, which excluded any coverage of the visit of a sitting US President to Boston. I think that raises a fair question about whether the paper is unbiased in its coverage of the President's visits," Lehrich wrote.
