The OGE, an independent branch dedicated to advising and aiding the executive branch in avoiding potential conflicts on interest and ethical violations, did not attribute the surge in contacts to any particular event beyond “recent events.” However, many observers have speculated that the increase is related to White House aide Kellyanne Conway appearing to use her position to promote the business brand of first daughter Ivanka Trump.

Conway’s comments drew sharp condemnation from oversight officials, with House Oversight Committee Chair and Republican Jason Chaffetz calling them “wrong, wrong, wrong, clearly over the line, unacceptable,” per the Associated Press. The Oversight Committee has since asked the OGE to review the comments.

When asked about them at Thursday’s press briefing, White House Press Secretary Sean Spicer said Conway had been “counseled” but provided no further details.

The Hill reports that a prominent liberal watchdog group, Citizens for Responsibility and Ethics in Washington, filed a complaint with the OGE soon after comments were made. Not long after, the agency’s website crashed. On Thursday evening, it went live again after several hours offline. Other media reports indicate that the office’s phone lines are all going straight to voicemail.
