In his own statement, Speaker Paul Ryan endorsed the move, and the decision to have Rep. Mike Conaway (R-TX) lead the investigation.
"I am confident that he will oversee a professional investigation into Russia’s actions and follow the facts wherever they lead," Ryan said.
Democrats said Nunes made the right choice.
"Good," was the simple tweet from Rep. Elizabeth Esty (D-CT).
"An important step in the right direction," said Rep. Jerry Nadler (D-NY), who like other Democrats have called for an independent probe.
"Nunes showed he was incapable of overseeing an independent investigation," Nadler added.
Today's developments stemmed from the events of a few weeks ago, when Nunes suddenly revealed that he had been given secret intelligence documents, as he announced that to reporters, and then dashed to the White House to brief President Trump.
In his remarks that day on Capitol Hill and at the White House, some thought that Nunes seemed to reveal classified information, as he confirmed the existence of a FISA wiretap - that drew outside ethics complaints, and now brings an official review from the Ethics Committee.
