Some of the most powerful Texas House Republicans said Monday they no longer support GOP Speaker Dennis Bonnen, marking the biggest blow yet to his political future amid the fallout from a secret recording released last week by a hardline conservative activist.

Five Republicans considered senior members of the lower chamber issued a statement withdrawing support for him: State Reps. Four Price of Amarillo, Dan Huberty of Houston, Lyle Larson of San Antonio, Chris Paddie of Marshall and John Frullo of Lubbock.

Sen. Marco Rubio was once one of Donald Trump’s most formidable opponents; now, the Florida senator bends over backward to excuse the president’s corruption.

In 2016, Rubio and Trump sparred frequently on the Republican primary debate stage. Trump picked the uninspired nickname “Little Marco” for the senator, which didn’t seem to do much damage on its own, but Rubio never gained the momentum or strength that his backers hoped would prove to be strong enough to take down the reality TV candidate. As Rubio grew desperate, he launched one of his most memorable and pitiful attacks by stooping to his opponent’s level, implying that Trump had a small penis. It was more of an embarrassing moment for Rubio than anyone else, though Trump helped himself with a crude rejoinder.
