Republicans in the US state of Missouri have begun a campaign to impeach the state’s governor for allowing same-sex couples to file joint tax returns.

Cole County Circuit Judge Jon Beetem, earlier in April heard arguments following a request for a temporary restraining order on an order given by the state’s Governor allowing same-sex couples to file joint tax returns.

Governor Jay Nixon filed the order in 2013, which made Missouri the first state which does not recognise same-sex marriages, to allow gay couples the right to file joint tax returns.

On Wednesday, a committee in the state will hold hearings into three formal complaints against Democratic Governor Jay Nixon.

The complaints argue that Nixon should be ousted as governor.

Republican Representative Nick Marshall accused Nixon of showing “a blatant and complete disregard for the will of the people”, through the move.

Two other complaints accuse Nixon of taking too long to call elections to replace General Assembly members and a third alleges that he insufficiently punished officials who handed over names of concealed weapons permit holders.

Despite the complaints, Nixon’s spokesman told the Associated Press that the attempts were just a “publicity stunt”.
