President Donald Trump made a "perfect" speech at the U.S. Holocaust Memorial Museum this week, putting to rest "absurd" charges he is anti-Semitic, retired Harvard Law professor Alan Dershowitz tells Newsmax TV.

"It was a perfect speech. The tone was perfect. The content was perfect. He then followed it a day or so later with a video to the World Jewish Congress in New York which was just as good," Dershowitz said Thursday to Newsmax TV's J.D. Hayworth.

"I think it puts to rest any of these absurd notions that Trump was an anti-Semite . . . That's always been foolish. I'm a liberal Democrat. I did not vote for Trump. I voted for Hillary Clinton.

"But right from day one I have been defending the Trump administration against these false charges of anti-Semitism. It's the Democrats who are being exploiting the Holocaust and exploiting anti-Semitism to make these charges."

During a Tuesday address at the museum's annual Days of Remembrance, Trump told the crowd of lawmakers, ambassadors, veterans and Holocaust survivors:

"I am deeply moved to stand before those who survived history's darkest hour. Your cherished presence transforms this place into a sacred gathering."

He added: "The survivors in this hall through their testimony fulfill the righteous duty to never forget and engrave into the world's memory the Nazi genocide of the Jewish people."

Trump's emotional remarks, Dershowitz said, made up for tone-deaf statements by Trump and White House press secretary Sean Spicer.

Spicer particularly riled Jews when he spoke of the use of chemical weapons in Syria, declaring that even Adolf Hitler hadn't stooped to using them during World War II, ignoring the fact that millions of Jews had been gassed.

"Those were honest mistakes by very busy people with not a lot of experience in the political crossfires. But to accuse them of Holocaust denial, anti-Semitism was an abuse to those important terms," Dershowitz said.

"So I'm glad that we can get back to assessing the Trump administration in its merits and put behind us these false charges of anti-Semitism and anti-Judaism, anti-Israel. It's just all political nonsense."

Dershowitz also said believe the ongoing push to move the American Embassy in Israel from Tel Aviv to Jerusalem will occur during Trump's term as president.

"It's about time. It should always have been in Jerusalem. Jerusalem is always the capital of Israel and Israel is the only country the United States doesn't recognize as a legitimate capital," the renowned civil-rights attorney said.

"The time is long overdue but it has to happen in context. What I'm hoping is the Trump administration is working diplomatically with the Saudis, the Emirates, the Jordanians, the Egyptians to come to a resolution.

"[One] that will allow the embassy to move without there being riots and violence. The last thing you want is the embassy to provoke, the embassy move to provoke another intifada or a break of the current subtle relations between Israel, the Emirates, Saudis, the Sunni Arabs who have a common enemy with Iran."

Dershowitz believes the move would counteract the Obama administration's "last petty act in office to allow a UN resolution to go through that basically says that the western world, the holiest site of Judaism, is illegally an occupied territory."

"That was the Obama administration's parting message to Israel, to Prime Minister [Benjamin] Netanyahu," Dershowitz told Hayworth.

"And the best response to that would be for the United States to make sure that our embassy is where it ought to be in west Jerusalem."
