“We are, in fact, disappointed by the decision that was announced today,” said White House deputy press secretary Josh Earnest to reporters aboard Air Force One en route to Michigan with the president.
The Supreme Court its 5-4 ruling in McCutcheon v. Federal Election Commission held that it was unconstitutional to limit the total amount of money individual donors could give to candidates, political parties and political action committees.
The high court, though, left standing rules that cap how much individuals can give to candidates and other laws requiring disclosure of donors.
The case was the latest to strike at campaign finance regulations and comes four years after the Citizens United ruling which struck down limits on independent campaign spending by corporations and unions.
Conservatives hailed the decision as a victory for free speech. But liberal groups said that ruling would give wealthy groups and individuals unfair sway in the political process.
President Obama has been a strong supporter of campaign finance laws, and criticized the Citizens United ruling in his 2010 State of the Union address, in front of many justices.
