I'm still told Baroness Warsi's job is safe tonight. But at the very least this has become awkward for the Prime Minister.
The co-chair of the Conservative Party is afterall the person David Cameron chose to enforce the Tory Party's rules. Both have spoken openly about the importance of transparency within politics.
As one Lib Dem peer told me, Baroness Warsi "should be above suspicion".
There are also some within her own party who don't think the Cabinet Minister is doing a particularly good job. I'm sure they would like to see her go.
But what's more difficult for David Cameron is that he already has another Cabinet Minister facing tough questions.
Culture Secretary Jeremy Hunt is due before the Leveson inquiry later this week over his links to News Corp and the BskyB bid. The PM could do without another minister in the dock.
