Members of the Supreme Court "put on an Obama jersey" when they upheld subsidies for Obamacare and made same sex marriage a Constitutional right Sen. Ted Cruz, R-Texas, told Chuck Todd on "Meet the Press" Sunday.

"In a period of 24 hours, we had two decisions of the Supreme Court where a majority of the justices violated their judicial oaths: In one, they ignored the text of Federal law; they rewrote Obamacare, forcing that failed law on millions of Americans," said Cruz passionately. "And then the next day, five justices disregarded the text of the Constitution, and purported to strike down the marriage laws in all 50 states."

Cruz said he agreed with Justice Antonin Scalia that these twin "decisions are an assault on democracy."

"I believe in democracy and the Constitution, and I think when the Supreme Court violates their oaths and undermines the Constitution, that is a grave threat to our nation," said Cruz, arguing in favor of his recommendation that Supreme Court justices should go through periodic elections.

Cruz said that the justices "have politicized the Court."

When Chuck Todd pushed back, asking if elections would politicize and polarize the Court further, Cruz said, "Look, we are polarized. And they [the justices] have seized political issues. They have become, effectively, politicians. And that's wrong."

Cruz said "reasonable minds can disagree" on the issue of gay marriage, but it is states that should decide the issue. "From the beginning of our country, literally from the first days of our country, marriage has always been a question for the states," said Cruz.

"If you want to change the marriages laws of your state, the Constitutional mechanism is to convince your fellow citizens to change the marriage laws," he said. "What that might mean, is that some states... [would] go one way and other states... they may go another way."

"It is profoundly troubling when you have Supreme Court justices not following their judicial oaths and taking the role of policy makers and legislators," said Cruz.
