Republican lawmakers plan to investigate mounting reports that federal officials are kicking families out of their homes and shuttering private businesses because they sit on federal parkland -- describing the spectacle as an over-the-top response to the partial government shutdown. 

"We are receiving a lot of reports" of businesses being shut down, said Mallory Micetich, spokeswoman for Republicans on the House Natural Resources Committee. 

She confirmed the committee is investigating these reports, as part of a widening probe into the National Park Service's response to the partial government suspension.
