Judicial Watch has filed a Freedom of Information Act lawsuit against the U.S. Secret Service over the agency's failure to provide records on the use of government funds for the Obama family vacation in Honolulu earlier this year.

Judicial Watch is an independent conservative non-profit group that focuses on waste, fraud and corruption in the federal government.

The group's original FOI request was sent on Jan. 2, 2013 seeking access to "All records concerning use of U.S. Government funds to provide security and/or any other services to President Obama and any companions on their January 1 and 2, 2013 trip to Honolulu, Hawaii." The Secret Service received the request on Jan. 11, 2013 and then acknowledged it on Jan. 31, 2013.

Judicial Watch sued after the Secret Service failed to respond within 20 days, as required by federal law, and has continued to withhold the requested records. The suit was filed in the U.S. District Court for the District of Columbia last week. You can read the court documents here.

Previously, Judicial Watch obtained documents concerning First Lady Michelle Obama's Africa trip in 2011 and her 2012 trip to Aspen, Colorado, but only after filing a similar lawsuit. A list of expenditures concerning First family vacations can be found on Judicial Watch's website. --- Kelly Cohen
