"This is the process working the way it was meant to, for the (president) to raise these issues and then discussions take place", Risch said.
President Donald Trump's pledge to use a U.S. base in Iraq to "watch" Iran has triggered a furious reaction from Baghdad.
In the same interview, the president also said the goal of the USA military presence in Iraq includes "watching" Iran - a comment that drew consternation from Iraqi leadership.
"We have to protect Israel", he told CBS News's Margaret Brennan on Sunday.
There are an 5,000 estimated U.S. military personnel in Iraq authorised to train, advise and assist Iraqi security forces in their fight against IS, which has not fully controlled any territory in the country for more than a year. It's perfectly situated for looking at all over different parts of the troubled Middle East.
The Republican-led U.S. Senate backed largely symbolic legislation on Monday that broke with President Donald Trump by opposing plans for any abrupt withdrawal of troops from Syria and Afghanistan. "We can come back very quickly".
Trump also indicated that he is not in sync with the assessment of his intelligence chief on the nuclear weapons programme of North Korea.

There was then reports that Irving is open to teaming up with James and his latest comments essentially put the icing on the cake. Irving and James defeated the Golden State Warriors together, but Irving eventually wanted to move on an make a name on his own.
The US decision to reimpose sanctions lifted under former president Barack Obama, as well as new measures targeting Iran's oil, banking and shipping industries has left Baghdad caught in the middle of growing tensions between its two biggest allies.
United States troops who stay in Iraq will also keep an eye on Syria, the president added.
"The United States calls upon other nations to repatriate and prosecute their citizens detained by the SDF and commends the continued efforts of the SDF to return these foreign terrorist fighters to their countries of origin", said State Department Deputy Spokesman Robert Palladino. "One of the greatest mistakes that we've ever made".
As part of its withdrawal plan, the USA has sought for all Iranian-commanded forces to exit Syria. Shiite-led Iran has strongly backed fellow Shiites who assumed power in Iraq after the 2003 US -led invasion deposed a regime headed by minority Sunni Muslims under dictator Saddam Hussein.
"I want to be able to watch Iran", he said. Reports later emerged saying he would be removing roughly half of the 14,000 U.S. forces stationed in Afghanistan, though sources noted how there were no set plans in the works. The US-led coalition, known as the Combined Joint Task Force - Operation Inherent Resolve (CJTF-OIR) had "low confidence" in those estimates as of last July, the report said.
The president acknowledged in the Sunday interview that there will still be "pockets" of fighters, but said, "You're not going to keep armies there because you have a few people or you even have fairly reasonable numbers of people".
However, the United States will not give up its bases in Iraq, he said.
