Presumptive Democratic presidential nominee Senator Barack Obama met with former rival Senator Hillary Clinton at her home in Washington on Thursday, according to media reports Friday.

The reports said it was "a small meeting" with perhaps just the two senators and a few aides in attendance.

There is intense speculation Obama might pick Clinton as his running mate for November's presidential election against Republican John McCain.

Obama said before that it's not in his best interest – or in the interest of Clinton – to make a hasty decision about whom his running mate will be.
