Texas Senator Ted Cruz has described Apple CEO Tim Cook's sexual orientation as a “personal choice.”

Cook, long rumored to be gay, broke his silence on his sexuality on Thursday in an essay published in Bloomberg Businessweek.

“I'm proud to be gay, and I consider being gay among the greatest gifts God has given me,” Cook, 53, wrote.

Cruz was asked to weigh in on Cook's announcement during an appearance on CNBC's Squawk Box.

“Those are his personal choices,” Cruz answered. “I'll tell you I love my iPhone.”

“Listen, Tim Cook makes his personal decisions, and that is his life. My focus is on the constitutional question of who has the authority to make decisions,” Cruz said.

Cruz, a Republican, stated that he believes marriage is best left up to the states, though he repeated his opposition to allowing gay and lesbian couples to marry and criticized recent Supreme Court decisions that paved the way for marriage equality in 16 states, 3 of which have yet to comply with appellate court decisions.

“This is something we've seen over and over again, which is the federal government and federal courts deciding they don't trust the people,” Cruz said. “They look down on the people, they don't trust us to make judgments about our own lives, so the federal government and federal courts are going to step in and impose their own policy preferences.”
