Sen. Ted Cruz (R-TX) on Monday brushed off Donald Trump’s threat to file a lawsuit over reports that Cruz may gain delegates won in the Louisiana primary by Sen. Marco Rubio (R-FL), who has since dropped out of the race.

“I’m always amused when Donald doesn’t know what to do and so threatens lawsuits,” Cruz said when asked about the potential lawsuit during a press conference in Wisconsin.

“Who cares? He can threaten whoever he likes,” the Texas senator continued. “I think the American people are getting tired of it.”

Cruz said that Trump does not know how to create jobs or keep America safe and “instead he yells and screams and curses.”

“It’s all a bunch of noise,” he added.

Following a report in the Wall Street Journal that the five delegates that had been awarded to Rubio in Louisiana would likely align with Cruz, Trump complained that Cruz was trying to “steal delegates” in a primary the real estate mogul won. Trrump then suggested he would file a lawsuit in a tweet, although it’s unclear who specifically he would sue.

During his Monday press conference, Cruz also addressed Georgia Gov. Nathan Deal’s (R) decision to veto a “religious freedom” bill that civil rights groups characterized as anti-LGBT. Cruz said Deal’s decision was “disappointing” and lamented that “it wasn’t long ago that religious freedom enjoyed bipartisan support.”

The Republican presidential candidate was also asked about calls for the Republican National Convention to allow attendees to carry guns. Cruz said that he hadn’t “reviewed” a petition to allow convention attendees to openly carry firearms, noting that the Secret Service has “the principal decision making concerning security.”

The Secret Service has said that firearms will not be allowed at the convention.
