Maryland marriage equality campaign received, besides the $250,000 from New-York's Mayor Michael Bloomberg, $1 million from the organization Human Rights Campaign.
The organization had recently announced to have collected $1 million which was going to be divided into 4 to help the various campaigns for marriage equality in Minnesota, Maryland, Washington and Maine.
This time-here, a spokesman of HRC said that besides the $250,000, the organization was going to add $950,000: $200,000 for Minnesota, $300,000 for Maryland and $225,000 for Washington and Maine.
"Our adversaries have bragged that marriage equality has never won at the ballot box," said HRC President Chad Griffin in a statement.
"This November, we will take that talking point away once and for all. In 2012, fair-minded Americans – and particularly residents of Maine, Maryland, Minnesota, and Washington – will support their LGBT friends, family members, and coworkers."
HRC is not the only organization to donate to help marriage equality campaigns, other groups like Freedom to Marry, the director of Amazon.com Jeff Bezos, Republican billionaires also contributed.
