The House GOP is pressing federal agencies for more information about President Obama’s climate change plans.

Energy and Commerce Committee Chairman Fred Upton (R-Mich.), along with other Republican members of the panel, sent letters on Thursday to 11 agencies requesting information about what their roles would be in Obama’s climate agenda.

Upton asked 13 agencies to attend a hearing on Obama’s climate change policies in September, but the Environmental Protection Agency and the Energy Department were the only two that showed up.

“Our oversight of the Obama administration’s climate activities will continue,” said Energy and Power subcommittee Chairman Ed Whitfield (R-Ky.) in a statement on Thursday. “Congress’ role is to conduct thorough oversight of agency spending and actions.”
