A trade deal that some say Senate Republicans are attempting to fast-track through Congress might contain controversial immigration procedures.

On Thursday, the Senate Finance Committee held what Americans for Limited Government President Rick Manning called an unscheduled and unannounced “secret” hearing to discuss whether to provide President Obama with fast track trade authority. “Fast track limits the constitutional requirement for treaty ratification to a simple majority rather than a two-thirds Senate vote requirement,” warned Manning.

Manning was surprised that, during the hearing, the U.S. Trade Representative Michael Froman said there would not be increased immigration under the TransPacific Partnership. The U.S. Trade Representative website specifically lays out details for expedited entries for temporary entry visas for workers from other countries.

“There has been bi-partisan agreement dating back until at least 2003 that trade deals should not touch U.S. immigration law,” explained Manning. During the hearing, the U.S. Trade Representative was questioned by Sen. Chuck Grassley (R-IA) on the issue of temporary entry provisions regarding immigration.

The U.S. Trade Representative provided Breitbart News with a rough transcript of the exchange:

A spokesperson from the U.S. Trade Representative told Breitbart News: “On the “general provisions” mentioned in the “Temporary Entry” section of the TPP outlines document on USTR’s website — as Ambassador Froman made clear in the hearing today — these are good governance provisions that U.S. practices are already consistent with and would require no changes to current U.S. practices.

And regarding the language stating: “specific obligations related to individual categories of business person are under discussion,” the spokesperson said, “that language was addressed by Ambassador Froman when he made clear that while other TPP countries are discussing ‘reciprocal agreements with each other’ the U.S. is not.”

The hearing took place Thursday morning and was officially announced Wednesday, according to the committee’s press office. Breitbart News attempted to contact Hatch’s office for comment about the short warning given to reporters.

Manning charges the TransPacific Partnership ignores Congress. “This is just one more reason for Congress to reject fast track legislation and subject this treaty to the full weight of Senate scrutiny as prescribed in the U.S. Constitution,” said Manning.

Curtis Ellis, Executive Director of American Jobs Alliance, echoes Manning’s concern.

Ellis said this language is complex and the fast tracked hearing is going to leave Congress with only 20 hours to review this complex legislation. Ellis said it ”makes legal language look like nursery rhymes.”

Ellis also said, “U.S. Trade Representative Michael Froman directly stated to Senator Grassley that the TransPacific Partnership would not include any changes on immigration and so-called ‘temporary entry’ foreign workers.”

But Ellis, like Manning, argues that this is not true.

“The U.S. Trade Representative’s own web site says the TPP includes an entire chapter to make it easier to bring foreign workers into the U.S. to take jobs that could be filled by Americans. Froman is either lying to Senator Grassley or he’s lying on his web site,” said Ellis.

Ellis explains that every free trade agreement that has been negotiated by the US Trade Representative since 1994 includes immigration provisions, but Congress has repeatedly said this is unacceptable.

“President Obama has said he will use every means he can to advance his immigration agenda, and has said he will bypass Congress to do it. You’d have to be pretty naïve to believe he is not using the TransPacific Partnership to do it,” charged Ellis. “This is yet one more reason for Congress to reject giving this president fast track trade promotion authority and hold this president accountable.”
