The lower house is controlled by the president's National Regeneration Movement (MORENA), which holds just over half of the 500 seats. Recent polls project that, although MORENA could lose some seats, it is likely to retain control of the house with the help of two allied parties.
National statistics agency INEGI said that adjusted for seasonal swings, Mexico posted a $249 million trade surplus last month after logging a deficit of nearly $3.4 billion in March.
A breakdown of the INEGI figures showed that Mexico sold $40.3 billion worth of exports in April in adjusted terms, 0.2% higher than the previous month, which was also a record.
Consumption of electricity, water and gas through pipelines rose 4.9% and manufacturing was up by 3%, the national statistics agency said. Mining activity, however, dipped by 3.1%.
Compared with the same month a year earlier, industrial output was 1.7% higher, driven by manufacturing.
Inflation jumped to 6.08% in April from 4.67% in March, national statistics agency INEGI said. A Reuters poll of economists had forecast a reading of 6.01%.
Inflation now stands at its highest rate since December 2017. The central bank targets inflation of 3%, with a one percentage tolerance range above and below that.
"For my part, I put myself at the full disposal of the authorities," said Ebrard, considered among the possible ruling party candidates for the 2024 presidential election.
"We are once again taking up dialogue to insist on this need," she said, ahead of an upcoming visit by Foreign Minister Marcelo Ebrard to the United States.
The US-Mexico border region, which stretches 3,175 km (1,973 miles), is home to at least 14.6 million people, according to government data from 2018.
The national statistics agency (INEGI) said consumer price inflation in the year through the first half of April rose to 6.05%, on the back of increasing energy and food, beverage and tobacco prices.
The figure beat the final consensus forecast of a Reuters poll of analysts for a headline reading of 5.84% and is the highest level since the 6.85% registered in the second half of December 2017.
"The jump in Mexico's headline inflation ... was driven once again by higher fuel inflation. We think this trend has a bit further to run, but the central bank is likely to look through this and keep its policy rate at 4.00% over the coming months," said Nikhil Sanghani, Latin America economist at Capital Economics.
Consumer prices rose 0.83% in March, according to non-seasonally adjusted figures.
