“Well the problem we’re having here is that there was a secret meeting in Louisiana of the convention delegation, and apparently all of the invitations for our delegates must have gotten lost in the mail," Trump adviser Barry Bennett told MSNBC's Ari Melber, Politico reported
"There’s a process to deal with this. It’s in the certification process, and it’s been with our legal team for most of the morning now, and we are moving forward with the complaint to decertify these delegates."
Trump on Sunday threatened a lawsuit over the delegate allocation from the Louisiana primary. Trump called Republican primary politics "unfair."
"Just to show you how unfair Republican primary politics can be, I won the State of Louisiana and get less delegates than Cruz - Lawsuit coming," Trump tweeted Sunday.

Bennett said on MSNBC on Monday that the complaint would be filed through the Republican National Committee. He said it's not something that you file in court.
"But it's a decertification so that these delegates and these rules committee member and folks don't get seated"," he said.
He said he doesn't know how long it will take attorneys to draft the complaint, but "we've got plenty of time."
"We're going to protect our rights to the fullest extent possible," he said. 
On Sunday, the executive director of Louisiana's Republican Party said the state GOP would be ready for a potential lawsuit from Trump.
“[I’m] really confident in the rules,” Jason Doré said on Sunday, according to The Times-Picayune. "[We] are taking it seriously and will be prepared.”
