According to Politico, Ted Cruz does not want to be president-elect Donald Trump’s Supreme Court nominee.

After Cruz spoke with Trump a week after Election Day, he and his chief of staff, David Polyansky met with Trump’s chief strategist Steve Bannon and rejected the potential nomination. Politico reported Cruz has been emerging as one of Trump’s key allies in the Senate instead.

A longtime Cruz friend commented:

I think the bottom line with Ted is that the monastic life of a Supreme Court justice is simply not something that appeals to him at this stage in his life and that’s notwithstanding the fact that he has already in his young legal career established himself as one of the nation’s premier Supreme Court advocates. But being on that side of the lectern is a different thing. He’s an advocate, he’s passionate about advancing the causes he believes in.

Cruz and Trump are already joining forces on key legislation and Cruz introduced fellow Texan Rex Tillerson to open his confirmation hearings for secretary of State before the Senate Foreign Relations Committee.

Cruz and Trump have also shared numerous connections among their key staffers. Bannon and Trump’s Deputy Campaign Manager David Bossie are longtime friends of the outspoken Texas senator.

In addition, Kellyanne Conway, ran a pro-Cruz super PAC early in the election and Trump’s transition aide, Jason Miller was Cruz’s communications director.

Cruz has already introduced legislation to defund that United Nations in retaliation for its Security Council’s resolution against Israeli settlements. Also, Politico reported Cruz has discussed two other pieces of legislation with Trump’s team: a call for term limits and another allowing donors to give unlimited contributions to political candidates on the federal level.

There was talk that Trump would encourage a primary battle against Cruz, but now, he’s eliminated at least one powerful candidate, former Texas Governor Rick Perry by nominating him as secretary of Energy.

The friend said:

That’s another negative to being a Supreme Court justice, it’s a lifetime commitment. Ted is not ready to lay down his sword an pick up a pen for the rest of his life.

In addition, it is uncertain if Cruz would have the votes he needed to get approved because a lot of House and Senate members have stated in the past they do not like him.
