KANSAS CITY, Missouri (CNN) -- Days before Congress' summer break begins, President Barack Obama planned to use a morning speech here to lambast Republicans who are preparing to sue him rather than taking action on some of his agenda items.
Democrats think they've struck fundraising gold with the Republican threat of a lawsuit against the White House, as well as the specter of impeachment some members of the party have raised. Since Friday, Democratic electoral committees sent more than a dozen e-mails using the issues to stir their supporters into donating money.
The Democratic Congressional Campaign Committee, tasked with electing Democrats to the House, said they'd raised more than a million dollars in online donations using the tactic.
House Speaker John Boehner announced plans earlier this summer to file suit against Obama for circumventing Congress on changes to his health care law, which some Republicans said was unconstitutional.
Obama has slammed the move as a political stunt, egging Republicans on with the quip "so sue me" during a speech in early July.
Separately, some Republicans have suggested Obama could be impeached for exceeding his authority as president, including former Alaska Gov. Sarah Palin and others in the conservative wing of the GOP.
Boehner wrote off any talk of impeachment as a Democratic fundraising ploy on Tuesday.
"They're trying to rally their people to give money and to show up in this year's elections," he said.
The White House was quick to cite a list of Republicans who have floated impeaching Obama, saying Boehner's description of the idea as simply a Democratic talking point ignored the statements of some of his members.
"If that's the case, then I suspect that there may be members of the Republican conference that didn't receive the memo," Press Secretary Josh Earnest said.
During his remarks on Wednesday at a historic theater, Obama will cast the Republican lawsuit as a distraction from the real work he wants Congress to be doing, including closing a legal loophole that allows big corporations to incorporate overseas to avoid paying U.S. taxes.
Obama has cast such tactics as unpatriotic in remarks over the past week.
After arriving in Kansas City on Tuesday, Obama headed to Arthur Bryant's restaurant for some of the city's signature barbecue. The establishment has served former Presidents Jimmy Carter and Bill Clinton, and its vinegar-based sauce is labeled "The President's Choice."
While he was there Obama met with four people who'd written him letters detailing their struggles and successes in the uncertain economy. Earlier in the day the White House released a video showing Earnest, a Kansas City native, calling the letter writers and asking them to join Obama at dinner.
Obama hopes to highlight the issues facing the middle class by scheduling meetings with Americans who have written him. This summer he's shared meals with people in Minnesota, Colorado, Texas and elsewhere.
At Arthur Bryant's on Tuesday, Obama ordered a half slab of ribs and a Bud Light, though when he asked for cole slaw the restaurant's staff told him they had run out.
"You didn't save me some?" he joked.
