"In an extraordinary public rebuke, two influential donors who were among the biggest supporters of Senator Ted Cruz’s presidential campaign excoriated Mr. Cruz on Saturday for his decision not to endorse Donald J. Trump at the Republican National Convention.
The remarks from Robert Mercer of Long Island and his daughter Rebekah Mercer suggest widening fallout over Mr. Cruz’s convention speech, in which he did not endorse his former rival and, instead, suggested that Republicans should “vote your conscience” for candidates “up and down the ticket.”
“Last summer and again this year, Senator Ted Cruz pledged to support the candidacy of the nominee of the Republican Party, whomever that nominee might be,” the Mercers, who rarely comment in the news media, said in the statement to The New York Times. “We are profoundly disappointed that on Wednesday night he chose to disregard this pledge.”
The statement continued: “The Democratic Party will soon choose as their nominee a candidate who would repeal both the First and Second Amendments of the Bill of Rights, a nominee who would remake the Supreme Court in her own image. We need ‘all hands on deck’ to ensure that Mr. Trump prevails.”
“Unfortunately,” the statement added, “Senator Cruz has chosen to remain in his bunk below, a decision both regrettable and revealing.”
The Mercers invested at least $11 million in Keep the Promise I, one of a group of interlocked “super PACs” that supported Mr. Cruz in his presidential run. During the contentious primary race, Mr. Cruz had early praise for Mr. Trump on the belief that his candidacy would eventually fade and that Mr. Trump’s voters would move over to the senator’s camp.
Instead, Mr. Trump’s candidacy endured and the race between the men grew increasingly rancorous.
Mr. Cruz is up for re-election in 2018 and is said to be looking at a second campaign for president in 2020, should Mr. Trump lose in November. But, in both cases, he will need his donor base to stay with him.
After Mr. Cruz’s speech at the convention in Cleveland, Sheldon G. Adelson, the casino magnate who was an early admirer of Mr. Cruz in the primaries, blocked him from his suite. (A friend of Mr. Adelson’s, claiming to represent him, insisted after the fact that he was not trying to disrespect the senator.)
A spokeswoman for Mr. Cruz, Catherine Frazier, said on Saturday:
“Senator Cruz considers Bob and Rebekah to be patriots and friends. As Senator Cruz urged in Cleveland, Hillary Clinton would be a disaster for America. Republicans need to unite, and the only way to unite is behind shared principles. His speech laid out a path — vigorously defending freedom and the Constitution — for our nominee to unite the party and for Republicans to win up and down the ticket.”
Mr. Mercer in recent weeks has helped fund a new effort for donors who want to defeat Mrs. Clinton, but who do not want to donate to a group that is openly supporting Mr. Trump. That group is being operated by David Bossie, the president of the group Citizens United.
Kellyanne Conway, who was the president of a pro-Cruz super PAC and now is an adviser to Mr. Trump, said the statement reflects the Mercers’ feelings about defeating Mrs. Clinton in the fall and “how grievously piqued they were to watch Ted’s convention stunt on Wednesday night.”
Ms. Conway added, “They supported Ted because they thought he was a man of his word who, like them, would place love of country over personal feelings or political ambition.”"
