'Get on the bandwagon': Trump slams 'unbelievably disloyal' GOP senators in overnight rant

President Donald Trump raged overnight against Republican senators he deems insufficiently loyal to him and his agenda.

The president singled out four GOP senators, including both from Kentucky, for considering a resolution that would end the national emergency he has used to impose a 25-percent tariff on Canadian imports, which will come to a vote Tuesday, which Trump has dubbed "Liberation Day" to mark the start of those punishing duties.

"Mitch McConnell of Kentucky, Susan Collins of Maine, Lisa Murkowski of Alaska, and Rand Paul, also of Kentucky, will hopefully get on the Republican bandwagon, for a change, and fight the Democrats wild and flagrant push to not penalize Canada for the sale, into our Country, of large amounts of Fentanyl, by Tariffing the value of this horrible and deadly drug in order to make it more costly to distribute and buy," Trump posted on Truth Social at 12:58 a.m. EST. "They are playing with the lives of the American people, and right into the hands of the Radical Left Democrats and Drug Cartels."

"The Senate Bill is just a ploy of the Dems to show and expose the weakness of certain Republicans, namely these four, in that it is not going anywhere because the House will never approve it and I, as your President, will never sign it," he added on Wednesday. "Why are they allowing Fentanyl to pour into our Country unchecked, and without penalty. What is wrong with them, other than suffering from Trump Derangement Syndrome, commonly known as TDS? Who can want this to happen to our beautiful families, and why? To the people of the Great States of Kentucky, Alaska, and Maine, please contact these Senators and get them to FINALLY adhere to Republican Values and Ideals. They have been extremely difficult to deal with and, unbelievably disloyal to hardworking Majority Leader John Thune, and the Republican Party itself. MAKE AMERICA GREAT AGAIN!"
