Misspoken again

The present perfect (he has spoken) is used either to indicate that something which occurred at an unstated moment in the past is in some way related to the present or to express that something began in the past but still continues at the moment and, most likely, into the future. Thus, when Connecticut attorney general and Democratic Senate candidate Richard Blumenthal says, "I may have misspoken, I did misspeak on a few occasions...I regret that I misspoke," he is sending a rather ambiguous message. Although he admits that he “did misspeak,” indicating that this is an issue of the past, he also says that he “may have misspoken.” Does he simply concede that his having misspoken contributes to his present troubles, or can we infer that his misspeaking, although it began in the past, continues at present and will go on in the future?
