Washington — Leading House Republicans announced on Tuesday two new probes, one into how the Obama administration’s Justice Department handled a deal that gave Russia control over 20 percent of the U.S. uranium supply, and the other into how it investigated Hillary Clinton’s use of a private email server when she was secretary of state.

The parallel investigations — both of which involve the House Oversight Committee working in cooperation with another panel — formally revive issues that the Trump campaign used to try to discredit his Democratic rival during the 2016 presidential race and later the conduct of former FBI director James Comey.

Democrats were quick to charge that the GOP-led probes were “designed to distract attention” from the various investigations into Russian meddling in the 2016 election, including alleged ties between the Trump campaign and the Kremlin.

The House judiciary committees’ probe into the Clinton email investigation focuses on well-established lines of questioning, including why Comey decided to publicly announce that the FBI was investigating Clinton but then waited months before making a similar announcement about its inquiries into Trump.

Panel leaders also promised to look into other aspects of the FBI’s timeline in deciding when to make key decisions and announcements regarding the Clinton investigation, including when the agency notified Congress about its status.

The House Oversight and Intelligence committees’ investigation also resurrects allegations that Clinton or others in the Obama administration mishandled a government decision to green-light a deal giving Russia control over a sizable percentage of the United States’ uranium resources. Intelligence Committee Chairman Devin Nunes, R-Calif., said on Tuesday that the panel has “been looking into this for a while now.”
