Senate Minority Leader Harry Reid spent much of a heated Monday speech on the Senate floor lighting into "Trumpet" Mitch McConnell and presumptive Republican presidential nominee Donald Trump.

After calling the Republican "capitulation" to Trump complete, he chastised McConnell, the Senate majority leader, for leading a supposedly "pro-Trump propaganda tour" the week before.

"Sen. McConnell spent last week as Donald Trump's head cheerleader — a trumpet," the Senate minority leader said. "The Republican leader left Washington 10 days ago without doing his job on Zika so he could stump for Trump."

"And in the last 10 days, it has become clear that Sen. McConnell will go to any length to support Donald Trump," he continued.

McConnell embarked on a recent media tour to promote his newly released memoir, "The Long Game."

Reid lambasted McConnell for not explicitly calling Trump's attacks against US District Court Judge Gonzalo Curiel racist during a Sunday "Meet the Press" interview. Trump has repeatedly insisted that Curiel's Mexican heritage makes it impossible to rule fairly in a Trump University case over which the judge is currently presiding.

Curiel was born in Indiana, but Trump has suggested that Curiel's background has made him impartial because of Trump's vows to build a wall along the US-Mexico border.

Trump later said that it was "possible" that a Muslim judge would also not be able to preside fairly over a case involving the presumptive nominee because of his proposed barring of Muslim immigrants.

"Donald Trump opined a federal judge should be disqualified from presiding on his case because of his Mexican heritage," Reid said. "He went even further in saying he would feel the same way if the judge were Muslim."

"And how did the Republican leader respond?" Reid continued. "Sen. McConnell repeatedly refused to say Donald Trump's attacks on Judge Curiel's ethnicity are racist. This is precisely the type of failure that gave rise to Donald Trump in the first place."

In a Sunday interview on NBC's "Meet the Press," McConnell said that he "couldn't disagree more" with what Trump has said about Curiel.

"This is a man who was born in Indiana," McConnell said. "All of us came here from somewhere else."

But McConnell would not call the attack "racist" when pressed repeatedly by host Chuck Todd.

"Sen. McConnell and all congressional Republican leaders have never taken a stand against Trump's vile rhetoric," Reid said.

"By refusing to denounce Trump's attack on a federal judge for the racism it clearly connotes, it shows Sen. McConnell is the poster boy for Republicans' spinelessness that allowed Donald Trump to be the Republican nominee for President of the United States," he continued.

Reid went on, insisting that McConnell was "too busy being a trumpet for Trump" to work on any legislative matters. He also said that there are many more questions for McConnell to answer after dodging the question of whether Trump's attacks against Curiel are racist.

In McConnell's newly released memoir, he dedicated a passage to his longtime Senate counterpart.

McConnell wrote:

If a scalpel will work, he picks up a meat-ax. He also has a Dr. Jekyll and Mr. Hyde personality. In person, Harry is thoughtful, friendly, and funny. But as soon as the cameras turn on or he's offered a microphone, he becomes bombastic and unreasonable, spouting things that are both nasty and often untrue, forcing him to then later apologize.
