Former Sen. Joe Lieberman on Thursday told Republicans and Democrats to get behind President Donald Trump's decisions to end the nuclear deal with Iran and to move the U.S. embassy in Israel to Jerusalem.
"I happen to agree with President Trump on these two decisions," Lieberman, a former Democratic and independent senator from Connecticut, said on CNBC's "Squawk Box" in an interview.
"Politics have become what they weren't when I became involved, which is the parties used to bring together people with different opinions and help to work with people from the other party to actually get things done," he added, going on to compare Democrats and Republicans to "warring tribes."
Lieberman went on to say that the agreement with Iran was "always a bad deal."
The senator, who remains a registered Democrat, added that he "worked a long time with a lot of other members of both parties in Congress to put those economic sanctions on Iran. They were intended to pressure Iran to give up its nuclear weapons program and to stop supporting terrorism and aggression in the Middle East. We gave up all that pressure on Iran for pretty much a pause in their nuclear program, and what turned out to be an acceleration of their other bad behavior."
He then addressed reports that European companies may pull out of Iran for fear of being sanctioned if they continue doing business there.
"We're still the strongest economy in the world. And whatever the political elites in Europe, for instance, are trying to do now to save the Iran nuclear deal, their businesses are speaking,"
He noted that the White House has relied on America's economic strength in its negotiations with China as well.
"The president does have leverage for China to renegotiate some of our trade agreements," he said before warning Trump: "Please don't let it go to a trade war because that could really hurt our economy [and] could hurt the global economy."
