The president, vice president and top administration officials have participated in 68 events benefiting 77 House incumbents, according to a memo the White House circulated this week.

The memo, which was obtained by Roll Call, was dated Tuesday and distributed to Capitol Hill Democrats following White House Press Secretary Robert Gibbs’ assertion Sunday that Republicans could win control of the House in the 112th Congress.

Gibbs’ remarks incited ire among House Democrats, and the memo appears to be an effort by the White House to push back by documenting the administration’s efforts on behalf of House and Senate Democrats.

It details 187 political events that President Barack Obama, Vice President Joseph Biden, first lady Michelle Obama, Cabinet officers or senior staff have participated in on behalf of Democratic lawmakers or challengers in the past 18 months.

According to the memo, the president has participated in four events benefiting nine House Members and 10 events for Senators. Biden has participated in 29 events to help 36 House Members and 16 events for Senators.
