Trump hails Supreme Court's partial reinstatement of travel ban 'clear victory for our national security'

— -- President Trump today joined supporters in declaring a “clear victory” after the U.S. Supreme Court agreed to allow parts of his travel ban to take effect.

While the ban will apply, effective Thursday, to people from the six predominantly countries listed on Trump’s March revised executive order -- Iran, Libya, Somalia, Sudan, Syria and Yemen -- who do not have a ”credible claim” of “bona fide connections” to the United States, the high court will also hear arguments on Trump’s travel ban when it reconvenes in October.

Here is a range of the reactions.

In support of the travel ban

President Donald Trump:

Today's unanimous Supreme Court decision is a clear victory for our national security. It allows the travel suspension for the six terror-prone countries and the refugee suspension to become largely effective.

As president, I cannot allow people into our country who want to do us harm. I want people who can love the United States and all of its citizens, and who will be hardworking and productive.

My number one responsibility as commander in chief is to keep the American people safe. Today's ruling allows me to use an important tool for protecting our nation's homeland. I am also particularly gratified that the Supreme Court’s decision was 9-0.

Counselor to the president Kellyanne Conway:

Attorney General Jeff Sessions:

I am pleased that the Supreme Court has decided to hear this case and the Department of Justice looks forward to arguing on behalf of the president and his constitutional duty to protect the national security of the United States.

We have seen far too often in recent months that the threat to our national security is real and becoming increasingly dangerous. Groups like ISIS and al Qaeda seek to sow chaos and destruction in our country, and often operate from war-torn and failed countries while leading their global terror network. It is crucial that we properly vet those seeking to come to America from these locations, and failing to do so puts us all in danger.

Against the travel ban

Director of the American Civil Liberties Union’s Immigrants’ Rights Project Omar Jadwat

“President Trump’s Muslim ban violates the fundamental constitutional principle that government cannot favor or disfavor any one religion. Courts have repeatedly blocked this indefensible and discriminatory ban. The Supreme Court now has a chance to permanently strike it down.”

Democratic National Committee Chairman Tom Perez

“Donald Trump’s Muslim ban is an unconstitutional and un-American assault on our country’s foundation of religious freedom. As a nation, our diversity is our greatest strength, and we cannot allow such prejudice to shut the doors of progress. Democrats will continue to fight this hatred every step of the way.”

Sen. Mazie Hirono, D-Va.

Sen. Patty Murray, D-Va.

Sen. Tim Kaine, D-Va.

Rep. Andre Carson, D-I.N.

Sen. Cory Booker, D-N.J.

Sen. Al Franken, D-M.N.

Minority Leader Nancy Pelosi

The Supreme Court’s move to largely lift the injunctions against the open prejudice of the Muslim and refugee ban sends the wrong message to our partners on the front lines of the fight against terror. We hope that the court will ultimately come to the only conclusion consistent with our values, our national defense and the Constitution.

Rep. Ruben Kihuen, D-Nev.
