India News: Sources said there is unease in the Congress over the controversies surrounding the two ministers, and a meeting of the core group was expected Saturday.

They said the core group could also informally meet Friday to take stock of the situation.

Party sources said Bansal's continuation in office would become untenable if the CBI decides to question him in the bribery case over the railway posting.

They said CBI investigators seem to be closing in on the minister.

"It would be embarrassing for the party if he were to be quizzed," a party leader said.

Sources said the party was looking at the direction the CBI investigations would take, and could ask Bansal to quit or ease him out in a minor cabinet reshuffle.
