hello!
heres what i found
There were a number of reasons why Seward should not have made the deal, but two that upset Congress were money and distance. Alaska was a good distance from Washington DC, and governing the territory would not only be difficult, but costly. Congress questioned who would live there and how would the US not only govern it, but protect it?
Then there was the price tag. The cost to purchases Alaska was seven million dollars. The Civil War had just ended in 1865, and the US had large debts resulting from that war. To pay out seven million dollars for a territory that didn't seem to have any real value was a big point of contention with Congress. Then there was the issue of the cost protecting, governing, and populating the territory. At the time, Congress saw the purchase as a big mistake.
have a goed day
