On the same day Sen. Elizabeth Warren (D-Mass.) appeared alongside Hillary Clinton to savage Donald Trump for his past statements, not to mention his "goofy hat," the presumptive Republican nominee's campaign fired back with another word for the liberal firebrand senator: "sellout."

"As Clinton tries to salvage support among the Bernie Sanders wing of the Democrat Party, Senator Elizabeth Warren (D-MA) has become a turncoat for the causes she supposedly supports," the campaign said in a statement with the subject line "Sellout Warren."


Noting that Warren has said Wall Street businesses have too much influence in Washington by paying "barely disguised bribes" as campaign contributions, the Trump campaign said Clinton has accepted more than $41 million during the presidential cycle from financial interests.

"Warren is also campaigning for the author of the Trans-Pacific Partnership, a deal she has routinely slammed," the statement continues, although Clinton has said she no longer supports the trade deal despite having backed it in principle. "This is a trade deal that Clinton has expressed support for in over 45 public speeches. Warren’s campaigning for Clinton stands in stark contrast to the liberal ideals she once practiced."

Calling the joint campaigning appearance a "sad attempt at pandering," the Trump campaign deemed it "another example of a typical political calculation by D.C. insiders."

"Mr. Trump has been against TPP from the start of his campaign because he understands how detrimental it would be to American workers," the statement concludes. "He will continue to fight for the American people and serve them over the special interests in Washington, D.C."

Trump is scheduled to deliver a trade-focused speech outside Pittsburgh on Tuesday, in Monessen, Pennsylvania.
