Donald Trump and Ted Cruz are planning to file a joint lawsuit challenging each other’s Supreme Court nominees, according to sources familiar with the plan.
The Trump campaign declined to comment.
Trump has repeatedly said he won’t seek a seat on the Supreme.
The Cruz campaign did not immediately respond to a request for comment.
Trump has said he’s opposed to a nomination of Judge Merrick Garland, who was nominated by President Barack Obama.
The pair have sparred over the future of Scalia’s legacy and their views on the role of the court in cases like Citizens United, which gave corporations and wealthy donors unprecedented power to spend unlimited sums of money.
Cruz has also vowed to appoint a replacement for Scalia.
The Republican National Committee, the primary conduit for the presidential race, has said it has not given the Cruz campaign any money.
The Cruz campaign has already spent more than $1 million on television advertising against Trump and has hired outside firms to target voters with negative messages, according the Federal Election Commission.
Trump and Cruz have been competing for the nomination in the wake of the election.
The Texas senator is considered the front-runner, while Trump is widely considered the presumptive nominee.
