A lawyer at Hogan & Hartson has been Bill and Hillary Clinton’s go-to guy for tax advice since 2004, according to documents released Friday by Hillary Clinton’s campaign.

New York-based tax partner Howard Topaz has had the job of preparing the couple’s annual tax returns for the last four tax cycles, the filings show. The Clintons’ tax returns for 2000-07 show combined earnings of $109 million, on which they paid $33 million in taxes.
