State Rep. James Spillane, from Deerfield, N.H., told NHJournal that Trump's criticism of McEnany prompted him to withdraw his endorsement of Trump and switch to challenger Ron DeSantis.
Trump's "most recent attack on Kayleigh McEnany is beyond comprehension and explanation," Spillane said. "Against my deepest hopes that Trump had learned some measure of control, he has attacked those who have been his staunchest supporters with no regard for their loyalty.”
In a Truth Social website post this week, Trump claimed his former spokeswoman misreported his poll numbers in a broadcast on Fox News.
"The RINOS & Globalists can have her. FoxNews should only use REAL Stars!!!" Trump said, drawing criticism from conservatives who usually have been sympathetic to the former president.
Trump also referred to his former spokeswoman as "Kayleigh 'Milktoast' McEnany," though the term is spelled "milquetoast."
Spillane appeared on stage with Trump in late April as the former president unveiled a group of New Hampshire endorsers. NH Journal also reported that "Spillane is the fourth state rep to flip from Trump to DeSantis in the past few weeks."
New Hampshire is expected to host the first Republican primary of the 2024 election season.
