The congressman leading an investigation intoreported Russian interference with last year's presidential electionhas temporarily stepped down from the investigation.Congressman Devin Nunes, a California Republican,said his decision follows the announcement of an investigation Thursdayby the House Committee on Ethics.The committee is looking into whether Nunes gave out classified information.Nunes called the charge "entirely false" and said it came from liberal activists.Democrats have been asking Nunes to give upthe chair of the House investigation into Russian interference.They are angry that he went to the White House on March 22to give information to President Donald Trump.He told Trump that American intelligence agencieshad recorded discussions by Trump aides.The information from Nunes led Trump to say he felt "somewhat" vindicatedabout his claim that he had been wiretapped by former President Barack Obama.Democrats objected that Nunes gave the information to the presidentand reporters before telling members of the House Intelligence Committee.They said the information came from the president's own staff.And the information did not support Trump's claims he had been wiretapped by President Obama.Replacing Nunes as leader of the House Russia investigationwill be Congressman Mike Conaway of Texas.Like Nunes, Conaway is a Republican.The investigation centers on reports from U.S. intelligence officialsthat Russia hacked into Democratic Party computersand released information to hurt Hillary Clinton's presidential campaign.Several people in President Trump's administration and his campaignhave faced questions about their Russian ties.Michael Flynn was Trump's national security adviser.He was fired after 23 days for misleading Vice President Mike Pence.Officials said Flynn had discussed sanctions with the Russian ambassadorbut he told the vice president that he had not.Flynn has offered to talk to congressional committees in return for immunity.Immunity means a person cannot be charged with a crimefor anything he says to Congress -- while under immunity.Paul Manafort is a longtime Republican adviserwho served as campaign manager for the Trump campaign.He stepped down three months before the election after questions were raisedabout his work for pro-Russian interests, particularly in Ukraine.Jared Kushner is President Trump's son-in-law, and an important White House adviser.He agreed to talk to Senate investigators.He is likely to be questioned about his meetingwith a Russian banker connected to Russian President Vladimir Putin.Jeff Sessions was an early supporter of Trump's presidential campaign.He was selected by Trump to be attorney general-- the top federal law enforcement job.Sessions announced he will not oversee the federal government's Russia investigation.He made the announcement after admitting that he failedto tell senators considering his nomination for attorney generalabout a meeting with the Russian ambassador.Roger Stone is described as a long-time friend of President Trump.During the 2016 presidential campaign,he predicted correctly that WikiLeaks founder Julian Assangewould release documents that would hurt Democrats.
