Mr Adams said Sir Hugh had support provided he did 'the right thing'
Gerry Adams has said the chief constable risks losing the support of the vast majority of republicans.
"He has the popular support of the vast majority of republicans, provided he does the right thing," the Sinn Fein president said.
Mr Adams said that to "open up the old agenda" was "not the way forward".
His comments come after Sir Hugh Orde requested the Special Reconnaissance Regiment's help to gather intelligence on dissident republicans.
The chief constable said he had asked for some extra support to deal with the threats posed by a small number of what he described as "extremely dangerous people".
Sir Hugh said he would discuss the move with the Policing Board next week.
In a statement on Saturday, Sinn Fein said it had spoken with the chief constable and "conveyed to him in no uncertain terms" its opposition "to this deployment and indeed the manner in which this has entered the public domain".
It said it had also been in contact with the British and Irish governments and would "continue in the time ahead to make them and others aware of the very real concerns and consequences of this retrograde decision".
