WASHINGTON (Reuters) - House of Representatives Speaker John Boehner said on Thursday that any unilateral steps by President Barack Obama to address a surge of illegal immigrants would make matters worse and add to a "legacy of lawlessness."
"No more unilateral action by the president," Boehner said at a news conference.
"If the president takes these actions, he'll be sealing the deal on his legacy of lawlessness," he said. "He'll be violating the solemn oath he made to the American people on the day of his inauguration."
Boehner said the House planned to vote Wednesday on legislation that would initiate a lawsuit against Obama for overstepping the bounds of his authority with unilateral actions.
Faced with an adversarial Congress, Obama has taken a series of unilateral actions to further his agenda. This has infuriated Republicans, who say Obama is exceeding the limits of his office. Boehner said Obama's actions were "sacrificing the integrity of our laws on the altar of political opportunism" and should be held accountable.
"The president's support is slipping and he and his party are desperate to motivate their base as we move toward the November elections," he said.
