Top Minnesota politicians from both parties signed and delivered the $39 million promise to the Republican National Committee back in January.
However, in the chaotic final moments of the legislative session many members received the bill just a few minutes before midnight and they were not allowed to debate it.
"We have the right to know what is in the bills! We have the right, madam speaker to know what is in the bills!" yelled Rep. Steve Sviggum.
The line of credit guarantee is a requirement for hosting a convention. Boston and New York City provided similar guarantees four years ago. However, Minnesota's credit line was never placed in a bill and did not get a hearing.
This issue may not matter, since the governor, for other reasons, might veto the entire tax bill.
The line of credit must be provided by August 1 of this year.
Late Tuesday afternoon the governor's office said it is looking into other ways to provide it, including getting a line of credit from the Met Council or a little known agency called the Public Finance Authority.
This is why the bill should have been debated.
